Description

The present invention generally relates to an information processing apparatus, a display control method thereof, and a program executed by a computer.

  Many displays for personal computers have a DDC (Display Data Channel) function. Such a DDC function is a function defined in the DDC standard for realizing an automatic environment setting function, a so-called plug and play method, on a computer system. According to the DDC standard, signal lines and procedures for exchanging data between a computer and a display monitor are defined. In other words, when a display that supports the DDC standard is connected to a computer, the computer extracts information related to the display necessary for plug and play (hereinafter referred to as EDID (Extended Display Identification DATA)) from the display by DDC communication with the display. It becomes possible.

  The EDID is stored in a nonvolatile memory such as an EEPROM (Electrically Erasable and Programmable Read Only Memory) inside the display, and includes information such as a manufacturer / product ID, display specifications, and support timing. In a computer system, in order to display an image on a display, information such as the resolution of the display is required. Such display-specific information such as display resolution and manufacturer name is referred to as EDID information. A communication method for acquiring EDID from a display is called DDC (Display Data Channel) communication, and an interface for DDC communication is called a DDC interface.

  The EDID has customizable fields. When the PC manufacturer wants to customize the EDID, since the EDID is written in the EEPROM at the time of manufacturing the display, it is necessary to instruct the display manufacturer to customize at the time of manufacturing the display. For this reason, when a display is provided from a plurality of display manufacturers for each PC model, the PC manufacturer needs to instruct customization of EDID for each PC model and display manufacturer.

  On the other hand, when a display manufacturer provides a display to a plurality of PC manufacturers or a plurality of PC models, it is necessary to customize the EDID for each PC manufacturer and each model and write it to the EEPROM. EDID management is complicated. Thus, at present, when customizing EDID, flexibility is poor for both the PC manufacturer and the display manufacturer, and management of EDID is complicated.

  The BIOS 41 reads the EDID from the LCD 31 through the video controller 15 using the DDC communication when the system is started. The BIOS 41 refers to the EDID table 42 and determines whether or not there is identification information of the read EDID, for example, EDID correction information corresponding to the Panel Name. If there is EDID correction information corresponding to the identification information of the read EDID, the BIOS 41 customizes the read EDID with the corresponding EDID correction information, and writes the customized EDID in the reference area 14 a of the system memory 14. Further, when there is no EDID correction information corresponding to the identification information of the read EDID, the BIOS 41 writes the Default EDID (the read EDID as it is) into the reference area 14 a of the system memory 14.

  The display driver 52 a controls the LCD 31 via the video controller 15 using the EDID (customized EDID or EDID of Default) written in the reference area 14 a of the system memory 14.

  FIG. 4 is a flowchart for explaining the outline of the process at the time of starting the BIOS 41. In the figure, first, the BIOS 41 reads the EDID from the EEPROM 32 of the LCD 31 at the time of starting the system (step S1), and whether or not the EDID correction information corresponding to the panel name of the DTD 4 of the read EDID exists in the EDID table 42. Is determined (step S2).

When EDID correction information corresponding to the Panel Name of DTD 4 of the read EDID exists in the EDID table 42 (“Yes” in step S2), the BIOS 41 customizes the read EDID based on the corresponding EDID correction information. The customized EDID is written in the reference area 14a of the system memory 14 (step S3).

  On the other hand, when the EDID correction information corresponding to the Panel Name of the DTD 4 of the read EDID does not exist in the EDID table 42 (“No” in Step S2), the BIOS 41 uses the read EDID as it is in the reference area of the system memory 14 14a is written (step S4). Thereafter, the OS 51 is activated (step S5). The display driver 52a controls the LCD 31 using EDID (customized EDID or EDID of Default) written in the reference area 14a of the system memory 14. Here, in order to collate with the EDID table 42, Panel Name is used as identification information in EDID. However, the present invention is not limited to this, and for example, Panel Name and Maker Name are used. You may decide to do it.

  FIG. 5 is a schematic diagram for explaining a specific example of customization of EDID. In the figure, a case where a panel such as Panel Name = “AAA12345”, “AAA67890”, or the like is supplied from the LCD manufacturer as the LCD 31 to the PC manufacturer will be described as an example.

  In the figure, the EDID of the LCD 31 includes ID = “AA1 (Maker ID)”, DTD1 = “vertical synchronization frequency 60 Hz Timing (clock frequency 72.3 MHz)”, DTD2 = “Blank”, DTD3 = “AAA (Maker Name). ) ”, DTD4 =“ AAA12345 (Panel Name) ”,“ CheckSum ”are set.

  For example, the PC manufacturer wants to customize the maker ID to “BB1” and the maker name to “XYZPad Display” for any LCD supplier LCD (to display “XYZ-Pad Display” on the LCD 31). ). Further, in order to reduce unnecessary radiation noise from the LCD 31, the notebook PC 1 has an experiment that the LCD with Panel Name = AAA12345 is effective to set the clock frequency to 69.3 MHz at the vertical synchronization frequency of 60 Hz Timing. I have confirmed that I want to customize the clock frequency to 69.3 MHz for the vertical synchronization frequency of 60 Hz Timing.

  Further, since the notebook PC 1 has a low power consumption mode that is driven at a vertical synchronization frequency of 50 Hz Timing, it is desired to customize the clock frequency at the vertical synchronization frequency of 50 Hz Timing to 57,75 Mhz. Similarly, in the case of an LCD with Panel Name = “AAA67890”, we want to customize the clock frequency at 75.2 MHz for the vertical synchronization frequency 60 Hz Timing and 62.65 Mhz at the vertical synchronization frequency 50 Hz Timing. Therefore, the EDID table 42 is configured as follows.

  The EDID table 42 stores EDID correction information 0, 1,. The EDID correction information 0 includes ID = “BB1 (Maker ID)”, DTD1 = vertical synchronization frequency 60 Hz Timing (clock frequency 69.3 MHz), DTD2 = vertical synchronization frequency 50 Hz Timing (clock frequency 57.75 MHz), DTD3 = “XYZPad” “Display (Maker Name)”, DTD4 = “AAA12345 (Panel Name)”, and “Checksum” are recorded. The EDID customization information 1 includes ID = “BB1 (Maker ID)”, DTD1 = vertical synchronization frequency 60 Hz Timing (clock frequency 75.2 MHz), DTD2 = vertical synchronization frequency 50 Hz Timing (clock frequency 62.65 MHz), DTD3 = “XYZPad Display (Maker Name)”, DTD4 = “AAA67890 (Panel Name)”, and “Checksum” are recorded.

  The BIOS 41 reads the EDID from the EEPROM 32 of the LCD 31 at the time of starting the system (step S1 in FIG. 4), and the EDID correction information of the Panel Name that matches the Panel Name = “AAA12345” of the DTD 4 of the read EDID is in the EDID table 42. (Step S2 in FIG. 4). Since there is EDID correction information 0 that matches the Panel Name = “AAA12345” of DTD4 of the read EDID (“Yes” in step S2 of FIG. 4), EDID ID = “AA1 (Maker ID)”, DTD1 = “vertical” Synchronous frequency 60 Hz Timing (clock frequency 72.3 MHz) ”, DTD2 =“ Blank ”, DTD3 =“ AAA (Maker Name) ”,“ Cheksum ”, ID of EDID correction information 0 =“ BB1 (Maker ID) ”, DTD1 = Vertical synchronization frequency 60 Hz Timing (clock frequency 69.3 MHz), DTD2 = Vertical synchronization frequency 50 Hz Timing (clock frequency 57.75 MHz), DTD3 = "XYZPad Display (Maker Name)", "Check Change to um "written in the reference area 14a of the system memory 14. The display driver 52 a controls the LCD 31 using the customized EDID written in the reference area 14 a of the system memory 14.

  As a result, the notebook PC 1 can display “XYZPad Display” on the LCD 31 as the Maker Name. Further, the LCD 31 can be driven at a clock frequency of 69.3 MHz at a vertical synchronization frequency of 60 Hz Timing, and unnecessary radiation noise can be reduced. Also, the LCD 31 can be driven with a vertical synchronization frequency of 50 Hz Timing (clock frequency 57.75 MHz).

  As described above, according to the first embodiment, the system memory 14 having the reference area 14a, the EDID table 42 in which the corrected EDID customized for the EDID is recorded for each of the plurality of LCDs, At startup, the EDID is read from the LCD 31 and the EDID table 42 is referenced to determine whether there is EDID correction information corresponding to the identification information (for example, Panel Name) in the read EDID. Customizes the read EDID based on the corresponding EDID correction information, and writes the customized EDID to the reference area 14a of the system memory 14 and the EDID written to the reference area 14a of the system memory 14 Based on the data to control the LCD 31. It is provided with the spray drivers 52a, to customize the EDID, PC manufacturers and improve both flexibility of LCD supplier, and it becomes possible to facilitate the management of the EDID.

  In addition, what is conventionally required to change the EDID (change of HW or FW) for each LCD manufacturer is changed by the BIOS of the notebook PC body in this embodiment, so the standard EDID of the LCD manufacturer LCDs with EDIDs for other companies can be used, and the flexibility of LCD manufacturers can be improved. In addition, since customization of EDID is performed on the BIOS, it is possible to customize for each system even with LCDs having the same EDID (even when using LCDs having the same EDID between different models, customization of EDID is possible for each model. Possible). In addition, changes to the display driver can be used with minimal or existing implementations.

  Further, since the EDID correction information includes the clock frequency of the LCD 31 that reduces the unnecessary radiation noise of the notebook PC 1, the unnecessary radiation noise of the notebook PC 1 can be easily reduced.

  Further, since the EDID correction information includes the manufacturer name, it is possible to easily display the customized manufacturer name.

  Further, when the EDID correction information corresponding to the identification information in the EDID read from the LCD 31 does not exist in the EDID table 42, the BIOS 41 writes the read EDID as it is in the reference area 14a of the system memory 14. Even when the EDID is not customized, the display driver 52a can control the LCD 31 by referring to the reference area 14a of the system memory 14.

  In the first embodiment, when the EDID correction information corresponding to the Panel Name of the EDID read from the LCD 31 does not exist in the EDID table 42, the read EDID is directly written in the reference area 14a of the system memory 14. On the other hand, in the second embodiment, when the EDID correction information corresponding to the Panel Name of the EDID read from the LCD 31 does not exist in the EDID table 42, the display driver 52a reads and reads the EDID from the LCD 31. The LCD 31 is controlled based on the EDID.

  In FIG. 6, the BIOS 41 reads the EDID from the LCD 31 when the system is activated, and determines whether or not the EDID correction information corresponding to the read EDID panel name is in the EDID table 42. When the EDID correction information corresponding to the Panel Name of the read EDID is in the EDID table 42, the BIOS 41 customizes the read EDID based on the corresponding EDID correction information, and refers to the customized EDID in the system memory 14 Write to area 14a. On the other hand, when the EDID correction information corresponding to the read EDID Panel Name is not in the EDID table 42, the BIOS 41 empties the reference area 14a of the system memory 14.

  When there is an EDID in the reference area 14a of the system memory 14, the display driver 32 controls the LCD 31 based on the EDID of the reference area 14a of the system memory 14. When the reference area 14a of the system memory 14 is empty, the display driver 32 reads the EDID from the LCD 31 via the video controller 15 by DDC communication, and controls the LCD 31 based on the read EDID.

  In the first and second embodiments, the LCD is used as the display. However, the present invention is not limited to this, and other displays such as plasma, organic EL, LED, and CRT are used. You may decide to do it. In the above embodiment, a notebook PC has been described as an example of an information processing apparatus according to the present invention.
