Description

Technical Field

[0001] The present invention relates to the technical field of electrostatic treatment of AMOLED display modules, and in particular to a method and system for repairing electrostatics of an AMOLED display module. Background Art

[0002] AMOLED display modules are more widely used in smart watch projects, and important brand customers are keen to use AMOLED display modules. The most prominent problem of AMOLED display modules on the client side is poor anti-static ability, so it is necessary to optimize the structure of AMOLED display modules to meet the requirements of the consumer market.

[0003] AMOLED display screen modules have poor anti-static ability. Traditionally, the client needs to add conductive cloth to strengthen the connection between the motherboard GND and the client's machine case. These actions will increase the introduction of material and labor costs, which will lead to increased customer costs and are not conducive to the promotion of AMOLED display screen modules. There are also methods that read the AMOLED Driver IC register to compare whether the value has changed. If the AMOLED is affected by static electricity and displays abnormally, the value set in the register in the AMOLED will also change at the same time. Therefore, the value of the specified register is read back and compared every 1 second to determine whether the AMOLED is affected by static electricity. However, since it takes 1 second to read back and compare, this greatly occupies the customer's motherboard CPU resources, thus affecting the customer experience. Summary of the invention

By configuring an static electricity detection unit in the AMOLED display module, the data value status of a specified register in the AMOLED display module is periodically detected. If the data value status of the register has not changed, a low level is output to the mainboard control module. If the data value status of any register has changed, a high level is output to the mainboard control module, thereby avoiding occupying CPU resources on the client side and solving the problem in the prior art that the cost will be increased by sticking conductive cloth to prevent static electricity, and the CPU resources of the client will be occupied by reading the register value, thereby reducing the user experience.

[0023] In the prior art, the use of conductive cloth to prevent static electricity will increase costs, and reading through register values ​​will occupy the client's CPU resources and reduce user experience.

[0024] In view of the above problems, a static electricity repair method and system for an AMOLED display module are proposed.

[0025] In a first aspect, a static electricity repair method for an AMOLED display module is provided. Figure 1 , Figure 1 This is a flow chart of an embodiment of a static electricity repair method for an AMOLED display screen module of the present application; it includes: Step 100, providing an electrostatic repair method for an AMOLED display screen module, including: a driving module (driving IC) of the AMOLED display module, and a mainboard control module (mainboard control IC); the driving module (driving IC) is connected to the mainboard control module (mainboard control IC), and the driving module (driving IC) includes an electrostatic detection unit (ESD check).

[0026] In the embodiment of the present application, an electrostatic detection unit (ESD check) is configured in the driving module (driving IC), and the AMOLED display module itself detects the data status of some registers according to the internal clock timing.

[0027] In a specific embodiment, Figure 2 , Figure 2 yes Figure 1 A flowchart of a specific implementation of step 100 in the embodiment; step 100 includes: step 110, obtaining a high-level interrupt IO port of a mainboard control module (mainboard control IC); step 120, electrically connecting an electrostatic detection unit (ESD check) to the high-level interrupt IO port through a detection IO.

[0028] In this embodiment, the electrostatic detection unit (ESD check) in the driving module (driving IC) realizes connection with the mainboard control module (mainboard control IC) by detecting IO and high-level interrupt IO port to perform level signal transmission.

[0029] Step 200 , the electrostatic detection unit (ESD check) periodically detects the data value state of a specified register in the AMOLED display module. If the data value state of the register does not change, a low level is output to the mainboard control module (mainboard control IC).

[0030] In a specific embodiment, Figure 3 , Figure 3 yes Figure 1 A flowchart of a specific implementation of step 200 in the embodiment; step 200 includes: step 210, the electrostatic detection unit (ESD check) obtains the data values ​​of all specified registers according to the internal clock at a regular time; step 220, the current data value of each register is compared with the initial value to determine the data value state.

[0031] For some registers for detecting display module abnormalities, such as 0x0A=0x08, 0XB0=0x00, and 0xF=0x00, the first is the register name and the second is the register data value. The data values ​​of these registers are detected regularly, and the current register data value is compared with the above initial value to determine whether the data status has changed. If it has changed, it means that the display module is abnormal.

[0032] Step 300: If the data value state of any register changes, a high level is output to the mainboard control module (mainboard control IC), and the mainboard control module (mainboard control IC) restarts the AMOLED display module to eliminate static electricity.

[0035] After restarting the display module, it is necessary to download the initial code to initialize the display module so that some of the above-mentioned stored data values ​​are restored to the initial values. By configuring an electrostatic detection unit (ESD check) in the AMOLED display module, the data value status of the specified registers in the AMOLED display module is regularly detected. If the data value status of the registers has not changed, a low level is output to the mainboard control module (mainboard control IC). If the data value status of any register changes, a high level is output to the mainboard control module (mainboard control IC), avoiding the occupation of CPU resources on the client side, and solving the problem in the prior art that the use of conductive cloth to prevent static electricity will increase costs, and reading through register values ​​will occupy the client's CPU resources and reduce the user experience.

[0038] Furthermore, the electrostatic detection unit (ESD check) includes a detection IO; the mainboard control module (mainboard control IC) includes a high-level interrupt IO port; The electrostatic detection unit (ESD check) is electrically connected to the mainboard control module (mainboard control IC) through the detection IO and high-level interrupt IO port.

[0039] Furthermore, the electrostatic detection unit (ESD check) is further used to: obtain the data values ​​of all specified registers according to the internal clock, and compare the current data value of each register with the initial value to determine the data value state.

[0040] Furthermore, the electrostatic detection unit (ESD check) is further used to: if the data value of any register changes, the level of the detection IO is pulled high, and the high level is transmitted to the high level interrupt IO port of the mainboard control module (mainboard control IC).

[0041] Furthermore, the mainboard control module (mainboard control IC) is further used to send a restart instruction to the driver module (driver IC) and initialize the register.

If the data value state of the register has not changed, a low level is output to the mainboard control module (mainboard control IC).
