DETAILED DESCRIPTION

[0047] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0048] Embodiment 1:

[0049] Please combine Figure 1-Figure 2 ,

[0050] Among them, the lowering device includes: AP01, USB line 02, touch debugging device 03, screen dot device 04, power wiring 05, mipi signal connection line 06, display reset reset connection line 07, incell display screen 08, driver IC 09, IIC signal line 10, touch reset 11;

[0051] The incell display screen 08 is connected to a driver IC 2 16 and a main busbar 13 , the main busbar 13 is connected to a backlight source 14 , and one side of the backlight source 14 is connected to an LED light bar 15 .

[0052] The implementation principle of the embodiment of the present application is: first use the screen-pointing device 04 to light up the incell display screen 08 on the screen-pointing device through the power connection 05 and the mipi signal connection line 06 and the display reset connection line 07, so that the driver IC-09 can work normally. When the incell display screen 08 works normally, the IIC of the driver IC-09 will communicate with the IIC host of the touch debugging device 03 through the IIC signal line 10 of the IIC signal and the touch reset 11, and then connect to AP01 through the data cable USB cable 02. The debugging program connected to the screen of the debugged touch device will be displayed on the computer for debugging the touch. There will be a driver IC-16 and a main cable 13 on the incell display screen 08. The main cable 13 is connected to the backlight source 14. The backlight source 14 has an LED light bar 15. The light bar 15 will be connected to the backlight drive power of the screen-pointing device to control the backlight on and off.

[0053] Embodiment 2:

[0054] The reduction method includes the following steps:

[0055] S1: Use the screen-pointing device 04 to light up the screen, use the mipi signal connection line 06 to connect the screen-pointing device 04 and the incell display screen 08, and then provide logic voltage and power supply, and then let the reset respond. Use the screen-pointing device 04 to light up the screen, and then provide logic voltage and power supply to the incell display screen 08, and then let the reset respond. The incell display screen 08 will light up first, and then let it display a white picture, that is, let its liquid crystal be completely inverted. Compared with other display pictures, the white noise will be larger.

[0056] S2: After the touch debugging device 03 lights up the incell display screen 08 normally through the mipi signal connection line 06, the incell display interface is connected to the touch part. The touch part is directly connected to the data channel Data and the clock channel clock through the IIC signal line 10, and the interrupt sends INT. After the interface mipi lights up the incell display screen 08 normally, it means that the display screen driver is working normally. Then the incell display interface is connected to the touch part. The touch part is usually an IIC interface, which directly connects its data channel Data, clock channel clock, and interrupts to send INT. If the touch reset of the screen driver IC is not processed, it is also necessary to connect the touch reset from the screen driver IC to the debugging device.

[0057] S3: After the touch and display wiring is completed, USB cable 02 connects the touch debugging device 03 and AP01, and turns on the host computer on AP01 to prepare for debugging.

[0058] S4: After debugging is completed, use the replacement device to replace the incell display screen 08 and perform continuous debugging.

[0059] In step S3, the device for lighting the screen adds thread control on the host computer so that when the display screen is touched, the backlight is turned off when the noise item under the screen off is debugged, and when the noise debugging item under the screen off is exited, the backlight is turned on again to debug other touch items.

[0060] The threads in thread control include:

[0061] void SystemThread() / / thread control program

[0062] {

[0063] SSD_SEND(0x11,0xB9,0x83,0x10,0xcomputer21,0x55,0x00); / / Code execution command to open

[0064] Delay(50); / / Delay 50ms

[0065] DCS_Short_Read_NP(0x0A,1,BUFFER+0); / / check polling register if(memcmp("0X08")) / / determine whether it is the default value 08

[0066] {

[0067] Delay(150); / / Delay 150ms

[0068] Set_POWER(1,1,1,0); / / 1.8V ON,2.8V ON,±6V ON,BL OFF Write_LCD_REG(0xFFFC,0xSealed box 2003); / / Fixed in one screen Delay(350); / / Delay 350ms

[0069] Write_LCD_REG(0xFFFC,0x2103); / / Fixed in one screen

[0070] }

[0071] if(!memcmp("0x08")) / / Judge if it is not the default value 08

[0072] {

[0073] Delay(100); / / Delay 100ms

[0074] Set_POWER(1,1,1,1); / / 1.8V ON, 2.8V ON, ±6V ON, BL ON

[0075] Delay(100); / / Delay 100ms}.

[0076] The above code is compiled on the host computer of the device with the display screen lit up. The purpose is to achieve that when debugging the noise under the off-screen state, the polling register sent by the screen can be recognized on the device that points to the screen. The recognition method is that when the screen is normally lit and the screen is normally lit, the value normally sent by the 0x0A register is 0x08, and when the screen is not off, it will return other values. Therefore, as long as the returned value is judged to be 08 or not 08 to use the thread to control the power on and off operation of the backlight, the backlight can be turned off when the screen is off.

[0077] At the same time, the noise debugging fails when the screen is off. At this time, the backlight is always on, and the LPWG Noise Test is NG!

[0078] Noise Max:204,Min:8

[0079] Va Touch Threshold:288,NoiseRatio_Va:50%,NoiseThreshold_Va:144

[0080] / / =========Out of Threshold in LCD Noise Test:

[0082] / / LPWG Noise Test is NG!

[0083] At the same time, the noise debugging pass is performed when the screen is turned off. At this time, the backlight will be turned off when the screen is turned off. LPWG NoiseTest is OK!

[0084] Noise Max:121,Min:8

[0085] Va Touch Threshold:288,NoiseRatio_Va:50%,NoiseThreshold_Va:144

[0086] / / LPWG Noise Test is OK!

[0087] Therefore, in the case of α-si process panels, when the firmware and code debugged by the IC factory cannot solve the noise when the screen is off, the factory uses a dot screen device and a touch debugging device. The debugging can reduce the noise of the Incell LCD screen by turning off the backlight when the screen is off.

[0088] Embodiment 3:

[0089] Combination Figure 3-6 The replacement device includes: the replacement device includes a transfer mechanism for transfer and a matching mechanism for debugging.

[0093] The outside of the debugging box 24 is fixedly connected to a protection box 23, and the outside of the protection box 23 is fixedly connected to a sealing box 20. The transfer mechanism and the matching mechanism are both located inside the sealing box 20. The protection box 23 is provided with a passage slot for the pneumatic cylinder 34 to pass through. The protection box 23 limits and protects the debugging box 24, and at the same time isolates the debugging box 24 to ensure the progress of the debugging work, and cooperates with the sealing box 20 so that the entire device can be better protected.

[0094] Conveyor belts 22 are connected to both sides of the sealing box 20. The two conveyor belts 22 are arranged in parallel.

[0097] The implementation principle of the embodiment of the present application is as follows: the display screen is placed on the conveyor belt 22 on one side for corresponding transportation, and then the adsorption nozzle 36 contacts the display screen on the conveyor belt 22 through the adsorption of the electromagnet 1 25 and the adjustment of the pneumatic cylinder 34, and at the same time the vacuum pump 26 works to produce a hollow state in the adsorption nozzle 36 and the magnet ring 35 for adsorption, and at the same time the execution circle 32 is driven by the motor 2 in the rotating circle 27 to rotate, so that the adsorption nozzles 36 on the execution circle 32 all adsorb the corresponding display screen, and during the adsorption feeding process, the timing regulator 37 on one side sends a signal to make the electromagnet 2 38 work, attract the magnet ring 35 to move, and then the telescopic rod 28 moves, and the display screen falls into the placement slot 39, contacts the lowering device, and performs corresponding debugging, and then the electromagnet The second iron 38 is energized in the reverse direction, so that the moving end of the telescopic rod 28 is retracted.

At this time, the vacuum pump 26 is powered off, so that the display screen falls into another conveyor belt 22, completing a cycle. Then the first motor drives the expansion circle 31, the extension rod 29 and the pneumatic cylinder 34 to rotate, so that the new display screen adsorbed on the conveyor belt 22 is moved to the top of the debugging box 24, and the debugged display screen enters the conveyor belt 22 on one side, and the empty adsorption nozzle 36 enters the conveyor belt 22 on the other side, and a periodic cycle is performed, thereby improving the overall work efficiency.
