In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.
The present invention provides a display panel, which includes but is not limited to a liquid crystal display panel, an organic light emitting diode display panel, a field emission display panel, a plasma display panel, and a curved panel, wherein the liquid crystal panel includes a thin film transistor liquid crystal display panel, a TN panel, a VA panel, an IPS panel, and the like.
Referring to fig. 1, in the embodiment, the display panel 200 is a liquid crystal display panel 200, and is used for a liquid crystal display module, and the liquid crystal display module is used for a liquid crystal display device 100, it should be noted that the liquid crystal display device 100 may be a liquid crystal television, a liquid crystal display, and the like, and the design is not limited thereto. In particular, in the present embodiment, the liquid crystal display device 100 is configured as a Vertical Alignment (VA) display mode, which is a display mode with advantages of high contrast, wide viewing angle, no rubbing alignment, and the like, as is well known, but the VA mode employs liquid crystals that rotate vertically, and the difference of birefringence of liquid crystal molecules is large, which results in a serious color shift problem at large viewing angles.
The current mainstream pixel design structure for improving color cast is eight domains and four domains: for the eight-domain pixel design, taking a first pixel unit and a second pixel unit which are vertically adjacent as an example, two four-domain regions are designed in any sub-pixel of the first pixel unit, and the two four-domain regions are respectively driven by a thin film transistor, so that the rotation angles of liquid crystals in the two regions are different, and the eight-domain wide-view display is realized; therefore, it is desirable to provide a four-domain pixel design method that can improve the viewing angle without decreasing the aperture ratio of the pixel.
In an embodiment of the present invention, referring to fig. 1 and 2, the display panel 200 includes:
the pixel unit comprises a plurality of sub-pixels 1, and the sub-pixels 1 are arranged in four domains; any one of the domain regions of the sub-pixel 1 includes a main region 11 (main pixel region) and a sub-region 12 (sub-pixel region) adjacent to each other; wherein,
the pixel electrodes in the main area 11 and the sub-area 12 are both arranged in an inclined stripe shape, and the inclination angle of the pixel electrodes in the main area 11 is different from that of the sub-area 12.
In this embodiment, each of the pixel units includes three sub-pixels of red, green and blue, and any one of the sub-pixels of red, green and blue is set in four domains. Conventionally, for any sub-pixel 1, the pixel electrodes in the four domains extend in different directions to compensate for color shift to some extent, and particularly, the pixel electrodes in the four domains are symmetrically arranged with respect to the adjacent sides of the two regions.
It is understood that at least one of the red, green and blue sub-pixels may be divided into the main region 11 and the sub-region 12, and in this embodiment, in order to improve the overall color shift prevention effect of the sub-pixels, the red, green and blue sub-pixels may be divided into the main region 11 and the sub-region 12, respectively. The pixel electrodes in the main area 11 and the sub area 12 are arranged in an inclined stripe shape, which is a design mode widely used in the liquid crystal display field, and has the advantages of simple structure, stable imaging and the like.
It is easy to understand that, by setting the tilt angles of the pixel electrodes in the main region 11 and the sub-region 12 to be different, when the sub-pixel 1 is switched on with a control voltage, the tilt angles of the liquid crystals corresponding to the main region 11 and the sub-region 12 are different, so that the transmittances of the main region 11 and the sub-region 12 are different, and we can make the liquid crystal cell have an eight-domain viewing angle compensation effect at different viewing angles.
According to the technical scheme, any domain area of the four-domain sub-pixel 1 is set to be the main area 11 and the sub-area 12 which are adjacent to each other, the pixel electrodes in the main area 11 and the sub-area 12 are arranged in an inclined stripe shape, the inclination angle of the pixel electrodes in the main area 11 is set to be different from that of the sub-area 12, therefore, when the sub-pixel 1 is connected with the same control voltage, the inclination angles of liquid crystals corresponding to the positions of the main area 11 and the sub-area 12 are different, so that the light transmittance of the main area 11 and the sub-area 12 is different, namely different brightness of the main area 11 and the sub-area 12 under the same voltage is formed, and on the premise that the pixel aperture ratio is not increased, the visual angle compensation effect of eight domains is achieved when a user watches the display panel 200 in different directions.
Alternatively, the inclination direction of the pixel electrode in the main region 11 is opposite to that of the sub-region 12; it can be understood that, with such an arrangement, on the one hand, it is beneficial to more clearly divide the main region 11 and the sub-region 12, so as to facilitate the process forming of the display panel 200, and on the other hand, it can better ensure that the inclination angles of the pixel electrodes of the sub-region 12 of the main region 11 are not consistent. It should be noted that the present design is not limited to this, and in other embodiments, the inclination direction of the pixel electrode in the main region 11 may also coincide with the inclination direction of the pixel electrode in the sub-region 12.
In this embodiment, the included angle between the pixel electrode in the main region 11 and the horizontal direction isThe pixel electrode in the sub-region 12 has an included angle with the horizontal directionAndsatisfies the following conditions:it can be understood that, with this arrangement, the difference between the light transmittances of the main area 11 and the sub area 12 is prevented from being too large, which may affect the viewing experience of the user. According to the formula of penetration rate(The azimuth angle between the absorption axis of the polarizer and the long axis of the liquid crystal molecules can be set as the absorption axis of the polarizer is generally parallel or perpendicular to the glass substrateUnderstood as the angle of the pixel electrode to the horizontal),the transmittance is the largest, so in this embodiment, the pixel electrode of the main region 11 is inclined to the horizontal direction, i.e. the included angleSet at 45 deg. to effectively enhance the imaging effect of the main zone 11, although, in other embodiments,other values of 30 ° to 75 ° may also be specifically set. In addition, in the present embodiment, the pixel electrode of the sub-region 12 forms an angle with the horizontal direction, i.e. the angleIs set to be greater than or equal to 9 DEG and less than or equal to 81 DEG, andis not equal toAs can be appreciated, the first and second,too large or too small a setting can result in too low a transmission of the secondary zone 12, so that its brightness is too low; in particular, it has been found through experimentation by the skilled person thatThe transmittance of the sub-area 12 is 70% of that of the main area 11 at 28.4 °, and the color shift prevention effect exhibited by the sub-pixel 1 is the best under this condition. It should be noted that the present design is not limited thereto, and in other embodiments,it is also possible to set the transmissivity of the sub-zone 12 to 10% to 99% of the main zone 11.
In this embodiment, main district 11 and subregion 12 are adjacent along the horizontal direction and arrange, can understand, so set up, on the one hand, conform to the rectangle design of conventional sub-pixel 1, are favorable to reducing the technology degree of difficulty of pixel to reduce display panel 200's manufacturing cost, on the other hand, correspond and improve more common display panel 200 horizontal direction large visual angle colour cast problem among the daily life. It should be noted that the design is not limited thereto, and in other embodiments, the main region 11 and the sub-region 12 are arranged adjacent to each other in the vertical direction to improve the problem of color shift of the display panel 200 in the vertical direction. In addition, in this embodiment, the main area 11 is located outside the sub-pixel 1 relative to the sub-area 12, and is configured such that the luminance of the area outside the sub-pixel 1 is greater than the luminance of the area inside the sub-pixel 1, thereby improving the effect of the whole image formation of the sub-pixel 1.
In the present embodiment, the area of the primary region 11 is smaller than or equal to the secondary region 12; it will be appreciated that this arrangement is advantageous to avoid the overall light transmittance of the sub-pixel 1 being too great. It should be noted that the design is not limited thereto, and in other embodiments, the area of the primary region 11 may be larger than the secondary region 12.
