Display and method for displaying pixels on a display device

The present invention relates to a display and a method for displaying pixels on a display device, and more particularly to a display having an image adjustment function and a method of adjusting and displaying an image on the display device.

In general, conventional displays allow the user to individually set display parameters for the display, such as brightness, chrominance, contrast, horizontal and vertical position, and even gamma correction gamma values. These settings apply to all parts of the image, including bright parts and dark parts. In other words, if the user wants to brighten the dark part, the settings performed for this purpose will also make the bright part brighter, and may even make the part too bright and become completely white. Similarly, when the bright portion is adjusted to be darker, part of the dark portion may be adjusted to be completely black. However, in most cases, the user only wants the dark part to be brighter or the bright part to be darker, and does not want to change the other parts of the image, and the above setting method cannot meet this requirement.

In view of the problems in the prior art, one of the objects of the present invention is to provide a method of displaying a plurality of pixels on a display device. This method can partially adjust the pixels according to the gray scale range, so it is suitable for adjusting only the pixels of the target part without changing the pixels of other parts.

The method for displaying a plurality of pixels on a display device of the present invention comprises: providing an image input of a gray scale to an original gray scale-luminance relationship corresponding to an image output of a brightness level, wherein the original gray scale-luminance relationship comprises a first input a grayscale range and a second input grayscale range, wherein the image input is represented by a grayscale quantity, and the first input grayscale range is higher than the second input grayscale range. The method also provides a first brightness adjustment relationship corresponding to the first input gray level range. Then, the method displays the pixels whose gray scale falls within the first input gray scale range on the display device according to the first brightness adjustment relationship, and simultaneously falls the gray scale within the second input gray scale range. The pixels are displayed on the display device according to the original gray scale-luminance relationship. Thereby, the plurality of pixels can be set by the user or according to the setting, only in a part of the gray scale range, for example, in the upper or middle gray scale range, rather than the entire gray scale range, relative to the original gray scale - The brightness relationship is adjusted. In practice, the plurality of pixels can be adjusted in multiple gray scales at the same time, for example, adjusting in a higher gray scale range and a lower gray scale range, so that the dark part of the image becomes brighter, and The bright part becomes darker, and this adjustment mechanism is very beneficial for instant games. Thus, the method of the present invention is capable of partially adjusting the image to address the problem of prior art adjustments that would create unwanted white or black.

Another object of the present invention is to provide a display capable of partially adjusting a plurality of pixels in accordance with a gray scale range. The plurality of pixels can therefore be adjusted only in the target portion without changing the pixels of the other portions.

The display of the present invention includes a display device. The display device includes a display panel And a control module electrically connected to the display panel. Providing a grayscale image input corresponding to an original grayscale-luminance relationship of the image output of the brightness level, the original grayscale-luminance relationship comprising a first input grayscale range and a second input grayscale range, the image input is one The gray scale indicates that the first input gray scale range is higher than the second input gray scale range. Providing a first brightness adjustment relationship corresponding to one of the first input gray scale ranges. The control module is configured to control the display panel to display a pixel whose gray level falls within the first input gray scale range on the display panel according to the first brightness adjustment relationship. At the same time, the pixels whose gray scale falls within the second input gray scale range are displayed on the display panel according to the original gray scale-luminance relationship. Therefore, the display can be set according to user requirements or settings, only in part of the gray scale range, for example, in the higher or middle gray scale range, rather than the entire gray scale range, relative to the original gray scale-luminance relationship pair. The plurality of pixels are adjusted. Similarly, in practice, the display can be adjusted in multiple gray scales at the same time, for example, adjusting the plurality of pixels simultaneously in the higher gray scale range and the lower gray scale range, and the adjustment mechanism is very Conducive to instant games. Thus, the display of the present invention is capable of partially adjusting the image to address the problem of prior art adjustments that would create unwanted white or black.

The advantages and spirit of the present invention will be further understood from the following detailed description of the invention.

Please refer to FIG. 1 and FIG. 2, which is a functional block diagram of a display 1 according to a preferred embodiment of the present invention. Figure 2 is a schematic view of the appearance of the display 1. The display 1 includes a display device 12 and an input device 14. The display device 12 includes a control module 122 and a display panel 124. The control module 122 is electrically connected to the display panel 124 and controls the display of the control module 122. The input device 14 is in communication with the control module 122. In this embodiment, the appearance of the display device 12 is implemented by a screen frame 126 and a bracket 128. The screen frame 126 is used to set the display panel 124. The bracket 128 is disposed on a desktop or the like, and is controlled. The module 122 is also disposed within the screen frame 126. The input device 14 can be separated from the display device 12 or connected to the bracket 128, and electrically connected to the control module 122 by a cable, such as a cable conforming to the USB standard. However, the invention is not limited thereto.

Please refer to FIG. 3, which is a flow chart of a method for displaying a plurality of pixels of an image on a display device according to a preferred embodiment of the present invention. In order to simplify the description of the method, the method shown in Fig. 3 is described by taking the display 1 shown in Figs. 1 and 2 as an example. In this embodiment, the method provides an original grayscale-luminance relationship of the grayscale image input corresponding to the brightness level image output according to the display characteristics of the display device 12, as shown in step S100 in FIG. The method also provides a first brightness adjustment relationship and a second brightness adjustment relationship, as shown in step S120. Then, the method displays the plurality of pixels on the display panel 124 by the control module 122 according to the first brightness adjustment relationship and the second brightness adjustment relationship and partly according to the original gray scale-luminance relationship. , as shown in step S140.

Please refer to FIG. 4 , which is a schematic diagram of the original gray scale-luminance relationship 20 and the first and second brightness adjustment relationships 30a, 30b. In this embodiment, the original gray scale-luminance relationship 20 is shown in thick figure in Figure 4. To simplify the description of the present invention, the original gray scale-luminance relationship 20 is represented by a straight line, but the invention is not limited thereto. The original grayscale-luminance relationship 20 includes a first input grayscale range 20a, a second input grayscale range 20b, and a third input grayscale range 20c. In general, the image input is represented by a gray scale. In this embodiment, the gray scale is equal to 256, that is, the image input is a grayscale value of 0 to 255. For convenience of explanation, the brightness step is represented by a value of 0 to 1, and therefore, the decimal point is applicable here; however, the present invention is not limited thereto. Wherein, the brightness step '1' represents a full load current or voltage display; the brightness step '0' represents a low current or voltage display, typically zero current or voltage. If the overload drive display is enabled, the brightness level can exceed 1. In the present embodiment, in order to simplify the description, the situation of the overload drive display is ignored here, but in practice, the present invention is still applicable to the case of an overload drive display.

In addition, the original grayscale-luminance relationship 20 is provided at the factory according to the display characteristics of the display device 12, that is, the original grayscale-luminance relationship 20 can be regarded as the gamma correction of the display device 12. In practice, the gamma correction is used to correct the visual distortion of the displayed image due to the display characteristics of the display device 12. Generally, the conversion relationship of the gamma correction is usually implemented by an exponential curve. Correction has an effect on the entire grayscale range, but the invention is not limited thereto. To simplify the illustration, the original grayscale-luminance relationship 20 is simplified to a straight line relationship, i.e., shown in a straight line in Fig. 4.

In this embodiment, the first brightness adjustment relationship 30a corresponds to the first input gray level range 20a, and the first input gray level range 20a is approximately 0.875 times the gray level quantity to 1 time of the gray level quantity, that is, Gray scale values 224 to 255; wherein the ratio '0.875' is about 224 At 255, the ratio '1' is approximately 255 divided by 255. The second brightness adjustment relationship 30b corresponds to the third input gray level range 20c, and the third input gray level range 20c is substantially from 0 times the gray level quantity to 0.125 times of the gray level quantity, that is, from the gray level value 0 to 32. Wherein the ratio '0' is about 0 divided by 255, and the ratio '0.125' is about 32 divided by 255.

For the first input grayscale range 20a, any input grayscale value (eg, grayscale value 34a) corresponds to an adjusted output luminance level value (eg, luminance order value 34b) according to the first luminance adjustment relationship 30a, and according to the original gray The order-luminance relationship 20 corresponds to an original output luminance level value (e.g., luminance order value 34c). The adjusted output luminance level value (i.e., luminance order value 34b) is less than the original output luminance level value (i.e., luminance order value 34c). Therefore, any portion of the image that belongs to the first input grayscale range 20a will be adjusted to be darker (ie, no original bright), which can be considered a white equalization.

For the third input grayscale range 20c, any input grayscale value (eg, grayscale value 34d) corresponds to an adjusted output luminance level value (eg, luminance order value 34e) according to the second luminance adjustment relationship 30b, and according to the original gray The order-luminance relationship 20 corresponds to an original output luminance step value (e.g., luminance order value 34f). The adjusted output luminance step value (i.e., luminance order value 34e) is greater than the original output luminance step value (i.e., luminance order value 34f). Therefore, any portion of the image that belongs to the third input grayscale range 20c will be adjusted to be brighter (ie, no original dark), which can be considered as a black equalization.

For the second input gray scale range 20b, that is, the remaining portion of the input gray scale range, the pixels whose gray scale falls within the range 20b are not adjusted, that is, according to the original gray scale-luminance Relationship 20 is displayed on display device 12. In addition, in practice, the gamma correction can be performed before the method is implemented, or can be implemented in conjunction with the adjustment of the method. In the latter case, the first and second brightness adjustment relationships 30a, 30b and the original gray scale-luminance relationship 20 can be integrated into a single relationship to simultaneously adjust (or convert) the plurality of pixels and display them on the display panel 124. However, the invention is not limited thereto.

Therefore, for an image, the aforementioned black balance can make the dark portion brighter, so that the user can recognize the detailed information of the dark portion; likewise, the white balance can make the bright portion darker. Allows the user to recognize the details of the bright part. This is good for the user to play the game, especially for real-time strategy games with bright and dark scenes. For example, an original scene, as shown in Figure 5, contains a dark portion (ie, one of the buildings on the right side of the broken window) and a bright portion (ie, a complete window of one of the buildings on the left side). After the original scene is adjusted by the method, the adjusted scene is as shown in FIG. 6, which shows that someone is hiding in the damaged window of the right building, and also shows that the other person is hiding in the complete window of the left building. After that, this image information is very important to the user. However, in practice, if the user only wants to watch the movie in the original image, the adjustment function based on the first and second brightness adjustment relationships 30a, 30b can be turned off.

Please refer back to Figures 1 to 3. The step S120 of providing the first and second brightness adjustment relationships 30a, 30b can be performed once for subsequent image use. In practice, the first and second brightness adjustment relationships 30a, 30b can be provided by the user. In the embodiment, step S120 is generally performed by a screen display menu 40 displayed on the display panel 124 of the display device 12. In practice, the screen shows that the menu 40 is a nested structure and Displayed by the control module 122 in a single column on the display panel 124 of the display device 12, as shown in FIG. The screen display menu 40 provides user two parameters for the black balance and the white balance, respectively. A white balance parameter plus a black balance parameter forms a pair, logically, each pair represents a brightness adjustment relationship. In other words, step S120 can be implemented by selecting the first and second brightness adjustment relationships 30a, 30b from a plurality of brightness adjustment relationships. The plurality of brightness adjustment relationships may be as shown in FIG. 8, wherein each arc-shaped dotted line represents a white balance parameter corresponding to the first brightness adjustment relationship 30a, or represents a black balance parameter corresponding to the second brightness adjustment relationship 30b. The black balance parameter and the white balance parameter can be individually selected.

In this embodiment, the user can directly operate one of the console panels 130 (shown in FIG. 2 with a dashed rectangle) or operate the input device 14 to display the menu 40 through the screen display menu 40 as needed. First and second brightness adjustment relationships 30a, 30b. In the latter case, the input device 14 includes a rotary member 142 (e.g., a scroll wheel), a confirmation button 144 (which is shown in phantom in Figure 2), a return button 146, and three switch buttons 148a, 148b, 148c. The confirmation key 144 is disposed under the rotary member 142 and can be triggered by pressing the rotary member 142. Switching keys 148a, 148b, 148c can be used as hot keys to correspond to user-preferred display parameters, including display parameters for black and white balance. In practice, the brightness adjustment relationship or/and the selected display parameter may be stored in a display mode, and the display module corresponds to one of the switch keys 148a, 148b, 148c, so that the switch key 148a, 148b or 148c can be Trigger to read the stored display mode to display the image. Additionally, in practice, the input device 14 can be wirelessly coupled to the display device 12, which facilitates the user's use of the input device 14. In addition, logically, lose Both the incoming device 14 and the console panel 130 are the same concepts of the input device of the present invention. The difference between the two is mainly that the input device 14 can be detached from the display device 12, and the console panel 130 is fixed to the display device 12.

In general, the adjusted image is typically displayed on display device 12 in a full screen size based on the specifications of display panel 124. However, for some reason, the user may prefer to display the adjusted image in a customized size. Therefore, before step S140, the method may also include the step of selecting a display size. In this embodiment, as shown in FIG. 9, the screen display menu 40 lists a plurality of display parameters including a full screen display parameter (shown as "Full" in FIG. 9), and an aspect ratio size display. Parameters (represented by "Aspect" in Figure 9), an original size display parameter (denoted in Figure 9 with "1:1"), and at least one non-equal aspect ratio predetermined size display parameter, as shown in Figure 9. Shown. The full screen display parameters are displayed in full screen size, that is, the displayed image extends across the display panel 124. The aspect ratio display parameter is used to display the largest of the same aspect ratios as the input image, that is, the width or length of the displayed image will reach the display limit of the display panel 124. The original size display parameter is used to display the same aspect ratio as the input image. For example, a 640×480 pixel image is displayed on the display panel 124 at 640×480 pixels. If the display 1 is a 24-inch display, the at least one unequal aspect ratio predetermined size display parameter may be composed of at least 17", 19", 19"W, and 22"W. Furthermore, it can be inferred that the area of the display parameter display with the unequal aspect ratio is smaller than the area displayed by the full screen display parameter.

In addition, in practice, the at least one unequal aspect ratio is displayed in a predetermined size. The parameters may further include, for example, 21.5", 23", etc., depending on the display area supported by the display panel 124. For example, "22"W" means that the image is displayed in the size of the image displayed on a 22-inch wide display, which has a wider display area than a typical 22-inch display. In practice, the actual display size of the 22-inch display may vary slightly from manufacturer to manufacturer, but still use the same nominal designation. This difference has been considered in the context of the present invention. The foregoing description of "22"W" also applies to the above-mentioned other display size nominal nomenclature, and will not be further described.

Therefore, the method selects one of the plurality of display parameters before step S140, as shown in step S160. In most cases, the full screen display parameter is mostly a preset value. Therefore, in practice, in the case of an instant game, the user usually selects one of the at least one unequal aspect ratio predetermined size display parameters. The adjusted image is displayed on the display panel 124 of the display device 12 with the selected unequal aspect ratio predetermined size display parameter. In other words, the selected unequal aspect ratio predetermined size display parameter is selected from the group consisting of 17", 19", 19"W, and 22"W. In addition, step S140 can be implemented independently of steps S100 and S120. Therefore, in the flowchart of this embodiment shown in FIG. 3, step S140 is performed in parallel with steps S100 and S120; however, the present invention is not limited thereto.

In addition, it is additionally noted that the user can also operate the input device 14 to select a display parameter (ie, select one of the at least one unequal aspect ratio predetermined size display parameter). For other descriptions of the operation of the input device 14, please refer to the related description of the input device 14 above, and details are not described herein again. Additionally, each of the toggle keys 148a, 148b, 148c may correspond to a display parameter. For example, in one case, the image is at least one non-equal height A switch key 148a, 148b or 148c corresponding to another non-equal aspect ratio predetermined size display parameter or the full screen display parameter may be triggered, such that the control module 122 switches to the other one of the predetermined size display parameters. The non-equal aspect ratio predetermined size display parameter or the full screen display parameter displays the adjusted image on the display panel 124.

It should be noted that the parameters of the foregoing display size may still not meet the needs of the user. Therefore, in practice, even if the user has selected a display parameter, the boundary of the display size of the display panel 124 can be further dynamically adjusted to meet the requirements. Its preferred display size is shown in Figure 10. In this embodiment, this dynamic adjustment can be implemented by the on-screen display menu 40. As shown in Fig. 10, the display size is enlarged by the same aspect ratio, but the invention is not limited thereto. For example, the display size can be scaled down by the same aspect ratio, or can be scaled up or down by any aspect ratio by adjusting each side of the border. In practice, the adjustment of the display size can be logically regarded as a continuous adjustment, even if the increment or decrement of the adjustment is a number of pixels or a single pixel. This boundary adjustment can also be performed by the input device 14 or the console panel 130. In practice, if the input device 14 can provide two-dimensional motion control, for example, the rotating member 142 is implemented as a trackball, the input device 14 can be regarded as a mouse, which is beneficial for the user to operate the input device 14. At this point, the user can scroll the trackball to drag the boundary.

As shown in the foregoing embodiment, in the foregoing embodiment, the pixels whose gray scale falls within the first input gray scale range 20a are displayed on the display panel 124 according to the first brightness adjustment relationship 30a; the gray scale falls in the third input gray scale range 20c. The pixels in the display are displayed on the display panel 124 according to the second brightness adjustment relationship 30b; the pixels whose gray scale falls within the second input gray scale range 20b are based on The original grayscale-luminance relationship 20 is displayed on the display panel 124. Conceptually, the control module 122 adjusts the pixels whose grayscale falls within the first and third input grayscale ranges 20a, 20c relative to the original grayscale-luminance relationship 20. In the foregoing embodiment, the first and second brightness adjustment relationships 30a, 30b respectively correspond to the first and third input gray scale ranges 20a, 20c, that is, the high gray scale range and the low gray scale range, but the present invention does not limit. In practice, the image can be adjusted according to more brightness adjustment relationships, or only adjusted according to a single brightness adjustment relationship. In an embodiment, the image may be adjusted based only on the first brightness adjustment relationship 30a or the second brightness adjustment relationship 30b. In another embodiment, the image may also be adjusted according to or only according to one of the brightness adjustment relationships 30c corresponding to an input grayscale range 20d (the grayscale value is from 112 to 144), as shown in FIG. The brightness adjustment relationship 30c is located between the first and second brightness adjustment relationships 30a, 30b (see FIGS. 4 and 8). In addition, the arc profiles corresponding to the brightness adjustment relationships 30a, 30b, 30c are also different for different purposes. For the intermediate brightness adjustment relationship 30c, one of the arcs is located above the original gray-scale relationship 20, and the portion of the arc is below the original gray-brightness relationship 20. In the present embodiment, as shown in Fig. 11, the portion of the image belonging to the brightness adjustment relationship 30c will be adjusted to a higher contrast, not for the case of all white or all black. This adjustment is useful for the user to read the part of the image. It should be noted that, in practice, the brightness adjustment relationship for adjusting the image is determined by a case, but the present invention is not limited to those disclosed in the foregoing embodiments.

The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
