Description

Register setting system of OLED driver IC

Technical Field

The invention relates to a setting technology of a driver IC, in particular to a register setting system of an OLED driver IC.

Background

For a DDI driving an OLED panel, it has many registers, and it is very important to quickly and accurately establish and verify these individual registers; in general, when the register of the DDI is set to an optimal value, the OLED panel can improve image quality; the existing test system is usually written in a text script form which can be identified by an OLED drive board; the prior art is not competitive enough since it is inefficient to obtain the optimum values of the registers for matching the OLED panel and the driver IC and difficult to accurately read, since these registers must be written to the text script in order to set the individual registers, and also include the settings of all the registers included in the address.

Disclosure of Invention

The invention provides a register setting system of an OLED driver IC, which can set a register of the driver IC by using a test system with an interface function, thereby processing OLED DDI with high precision and high speed.

In order to solve the above technical problems, the register setting system of an OLED driver IC of the present invention includes a driver IC, an OLED driver board, and a test system for setting registers of the driver IC and the OLED driver board, the test system can set all registers individually by reading an Excel file containing all register information of DDI, and the OLED driver board can convert control data output by the test system into MIPI interface signals for the OLED driver IC.

The test system includes a register control window for setting a single register, a text script window for setting a plurality of registers, and a display window for transmitting display image data.

The register control window contains information about each register and editing controls.

The text script window contains an edit control for setting a plurality of registers, the edit control being in a text script format.

The display window includes a control button that can display a thumbnail image stored in a PC having a function of transferring image data.

The register control window includes an open button of an Excel file capable of reading information on all registers of the driver IC, a read button for reading register setting values, a register name unit distinguishing the respective registers, and an edit control module capable of writing register names and setting values by reading information in the registers of the Excel file and the read button.

The invention has the advantages that:

the method can be used for effectively matching the OLED panel and the driver IC by setting the independent register, in addition, when the OLED driver IC needs to be changed, the program of a test system does not need to be modified, only an extra Excel file needs to be developed (only the Excel file needs to be created when the DDI is changed), meanwhile, because the interface which is the same as the interface of the existing environment can be kept, the interface of the same environment can be kept unchanged as before, and the change is not needed, so that the OLED DDI can be processed at high precision and high speed, and the development cost and the development period are greatly reduced.

Detailed Description

The register setting system of the OLED driver IC of the present invention will be described in further detail with reference to the accompanying drawings and embodiments.

As shown in the figure, the register setting system of OLED driver IC of the present invention is a solution for providing a set register by automatically generating a control without modifying the source code of the program of the test system, a set IC is selected from the driver ICs, and it includes a driver IC (chip) 12, an OLED driver board 11, and a test system 10 for setting the registers of the driver IC12 and the OLED driver board 11, the test system 10 includes a register control window 14 for setting a single register, a text script window 15 for setting a plurality of registers, and a display window 16 for transmitting display image data, the register control window 14 contains information and edit controls about each register, as can be seen from FIG. 2, the register control window 14 contains an open button 21 of an Excel file capable of reading information about all registers of the driver IC, a read button 22 for reading all register setting values, A register name unit 23 for distinguishing each register and an edit control module 24 for distinguishing a setting value of the register name unit 23 and the edit control module 24 for each register, which can be changed by a keyboard after generating an edit control, a text script window 15 containing an edit control for setting a plurality of registers, which is in a text script format, a display window 16 containing control buttons for displaying thumbnail images stored in a PC having a function of transferring image data, a display window 16 generating buttons for identifying the picture data stored on the PC as thumbnail icons, which can be transferred by pressing the buttons, by which the test system 10 can read an Excel file containing information of all registers of DDI (generate edit controls for setting each register) and can set all registers individually, the OLED driver board 11 can convert the control data and the picture data output by the test system into MIPI interface signals used on the OLED driver IC12, and transmit them to the driver chip, and, by this technical solution, the program of the test system generates a control to individually set all registers by reading an Excel file containing all register information of DDI, and thereafter, by setting the individual registers based on the generated register control (how they are generated), the time required for verification is shortened, in particular, by which the program of the test system will be marked with the name of each register, the corresponding setting value is generated as an editing control 24, and the names 23 and the setting values of all registers on the register control window 14 after reading the Excel file recording the setting value are generated as the editing control 24, with respect to the names, the index addresses, the bit size of the setting value, and the bit position of all registers of the DDI.

Further, as can be seen from fig. 2, fig. 2 shows an execution interface of the register control window 14 for setting registers of the driver IC, the register control window 14 includes an open button 21 of an Excel file capable of reading information on all registers of the driver IC, a read button 22 for reading all register set values, a register name unit 23 for distinguishing respective registers, and an edit control module 24, the edit control module 24 is capable of writing the register name 23 and the set values by reading the information in the registers of the Excel file and the read button 22, as described above, when the edit control module (edit control) 24 of the registers is written with the set values and operated, the Enter (Enter) key is operated to send a text script that is converted to be recognizable by the OLED drive board 11, and the number of pictures is transferred in the display window 16 after the OLED panel 13 is initialized if an initialization code that can drive the OLED drive chip 12 is transferred in the text script window 15 Accordingly, when the picture on the OLED panel 13 is displayed, the setting value of the register control disposed in the register control window 14 for optimizing the picture quality of the picture displayed on the OLED panel 13 can be changed to optimize the OLED driving chip in a shorter time than the conventional method.
