[0002] As the market demands increasingly higher quality for display module products, in order to trace the current testing records of each product (customer's material code, supplier, rework, production line, production date, etc.), a programming fixture is usually used; this allows for the programming of electronic QR code information and VCOM / FLK / single gamma / 3gamma on the display module.

[0003] The existing burning fixtures require manual power-on, manual barcode scanning, and manual burning. Each operator can only operate one fixture, which is very inconvenient and wastes a lot of manpower and resources. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an OTP programming fixture for display modules.

[0005] This utility model provides the following technical solution: an OTP programming fixture for a display module, comprising a frame, a limiting frame disposed on the frame, a space formed in the middle of the limiting frame for accommodating the display module, a sliding frame slidably connected to the frame, a barcode scanner and a probe disposed on the sliding frame, a lamp testing machine disposed on the frame, an adapter plate for connecting to the flexible circuit board of the display module, and a programming assembly electrically connected to the barcode scanner and the probe; the adapter plate is electrically connected to the lamp testing machine; the barcode scanner is used to acquire QR code data on the display module; when the sliding frame moves towards the limiting frame to its limit position, the probe is directly facing the center of the limiting frame; the OTP programming fixture also includes a switch disposed on the frame, the switch being used to control the start and stop of the barcode scanner, the probe, and the lamp testing machine.

[0006] Furthermore, the frame is provided with a plurality of first slide rails, and the sliding frame is slidably connected on the first slide rails.

[0007] Furthermore, protrusions are formed on the upper sides of both ends of the first slide rail, and the first slide rail as a whole is U-shaped.

[0008] Furthermore, a notch is formed on one side of the limiting frame, and when the display module is placed into the space formed in the middle of the limiting frame, the flexible circuit board of the display module is led out from the notch.

[0009] Furthermore, the switch is a push-button switch, and when the sliding bracket moves to its limit position in the direction of the limiting frame, the sliding bracket presses the push-button switch.

[0010] Furthermore, the side of the sliding bracket closest to the button switch has an arc-shaped surface.

[0011] Furthermore, the adapter plate includes a main body that is electrically connected to the lamp sensor, a cover plate that covers the main body, and a fixing component for fixing the cover plate; the flexible circuit board of the display module is electrically connected to the main body.

[0012] Furthermore, the fixing component includes a second slide rail disposed on the frame and a sliding block slidably connected to the second slide rail; when the cover plate is placed on the main body, the sliding block is slid to the upper side of the cover plate, thereby fixing the cover plate.

[0013] The beneficial effects of this utility model are as follows: By pushing the sliding frame to move closer to the display module, the sliding frame drives the barcode scanner and probe to move closer to the display module. When the sliding frame moves to its limit position, the probe is directly facing the center of the display screen of the display module, and the arc surface on the sliding frame will press the button switch. When the button switch is pressed, it will start the control lamp tester, the barcode scanner, and the probe. The barcode scanner scans the information on the QR code, and the probe obtains the data from the display module for the burning process. Thus, by simply pushing the sliding frame, the barcode scanner and probe can work simultaneously to complete the burning process, achieving the effects of saving manpower and convenient operation.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] An OTP programming fixture for display modules, such as Figures 1-3 As shown, the device includes a frame 1, a limiting frame 9 on the frame 1, a space formed in the middle of the limiting frame 9 for accommodating the display module 8, a sliding frame 3 slidably connected to the frame 1, a barcode scanner 4 and a probe 5 on the sliding frame 3, a lamp testing machine 6 on the frame 1, an adapter plate 7 for connecting to the flexible circuit board 82 of the display module 8, and a programming assembly electrically connected to the barcode scanner 4 and the probe 5; the adapter plate 7 is electrically connected to the lamp testing machine 6; the barcode scanner 4 is used to acquire data of the QR code 83 on the display module 8; when the sliding frame 3 moves to its limit position towards the limiting frame 9, the probe 5 is directly facing the center of the limiting frame 9; the OTP programming fixture also includes a switch 10 on the frame 1, the switch 10 is used to control the start and stop of the barcode scanner 4, the probe 5 and the lamp testing machine 6.

[0023] It is understandable that OTP is an abbreviation for One-Time Programmable, which is a type of memory for MCUs, meaning one-time programming. In the production of display module 8, in order to eliminate the screen jitter phenomenon of display module 8, OTP programming is required. In order to ensure that each display screen 81 is at the minimum flicker level, the LED tester 6 is required to test the flicker level of display screen 81 while adjusting the common mode signal voltage until the flicker level reaches the minimum. Then, the common mode signal voltage value is programmed into display module 8.

[0024] The frame 1 is provided with a plurality of first slide rails 2, and the sliding frame 3 is slidably connected to the first slide rails 2; the upper sides of both ends of the first slide rails 2 are formed with protrusions, and the first slide rails 2 are generally U-shaped; a notch is formed on one side of the limiting frame 9, and when the display module 8 is placed in the space formed in the middle of the limiting frame 9, the flexible circuit board 82 of the display module 8 is led out from the notch; the switch 10 is a push-button switch 10, and when the sliding frame 3 moves to the limit position in the direction of the limiting frame 9, the sliding frame 3... The button switch 10 is pressed; the sliding frame 3 has an arc-shaped surface 31 on the side near the button switch 10; the probe 5 is used to acquire relevant data on the display module 8 to be programmed; the lamp testing machine 6 is used to complete the functions of control, data acquisition processing, testing, lighting and programming of the display module 8; the probe 5 and the lamp testing machine 6 are existing technologies and will not be described in detail here; the barcode scanner 4 is used to scan the QR code 83 on the display module 8. The QR code 83 is mainly for a series of information of a single display module 8, such as "customer's material code, supplier, rework, production line body, production date";

[0025] Understandably, when this fixture is needed, the display screen 81 of the display module 8 to be programmed is placed inside the limiting frame 9, and the flexible circuit board 82 of the display module 8 is led out from the notch and connected to the adapter plate 7. Then, the operator can push the sliding frame 3 to move closer to the display module 8. The sliding frame 3 drives the barcode scanner 4 and the probe 5 to move closer to the display module 8. When the sliding frame 3 moves to its limit position closer to the display module 8, the probe 5 is directly facing the center of the display screen 81 of the display module 8, and the arc on the sliding frame 3... When surface 31 presses the button switch 10, the button switch 10 is pressed, which will start the control lamp tester 6, the barcode scanner 4, and the probe 5. The barcode scanner 4 scans the information on the QR code 83, and the probe 5 obtains the data of the display module 8 for burning. After burning is completed, the operator can slide the sliding frame 3 to move away from the display module 8. At this time, the sliding frame 3 will no longer press the button switch 10. At this time, the lamp tester 6, the barcode scanner 4, and the probe 5 are all in the off state. Then the operator can take the display module 8 out of the limit frame 9.

[0026] like Figure 4 As shown, the adapter plate 7 includes a main body 72 electrically connected to the lamp testing machine 6, a cover plate 71 covering the main body 72, and a fixing component for fixing the cover plate 71; the flexible circuit board 82 of the display module 8 is electrically connected to the main body 72; the fixing component includes a second slide rail 73 provided on the frame 1, and a sliding block 74 slidably connected on the second slide rail 73; when the cover plate 71 is placed on the main body 72, the sliding block 74 is slid to the upper side of the cover plate 71, thereby fixing the cover plate 71.

[0027] It is understood that the cover plate 71 is rotatably connected to the main body 72 or the frame 1. By rotating the cover plate 71, the cover plate 71 is placed on the main body 72. The operator can rotate the cover plate 71 so that the cover plate 71 is no longer placed on the main body 72. Then, the flexible circuit board 82 of the display module 8 is electrically connected to the main body 72. Next, the cover plate 71 is rotated to place the cover plate 71 on the main body 72. Then, the operator can slide the sliding block 74 to move the sliding block 74 towards the cover plate 71, thereby moving the sliding block 74 above the cover plate 71. At this time, the cover plate 71 will be unable to... Rotate the cover plate 71 away from the main body 72 to fix it on the upper side of the main body 72, preventing the flexible circuit board 82 from slipping off the main body 72. When it is necessary to remove the flexible circuit board 82 from the main body 72, the operator can slide the sliding block 74 to move the sliding block 74 away from the cover plate 71, so that the sliding block 74 is no longer on the upper side of the cover plate 71. Then the operator can rotate the cover plate 71 to remove it from the upper part of the main body 72. Then the connection end of the flexible circuit board 82 of the display module 8 can be removed from the main body 72.

[0028] In summary, by pushing the sliding frame 3 towards the display module 8, the sliding frame 3 drives the barcode scanner 4 and the probe 5 to move towards the display module 8. When the sliding frame 3 moves to its limit position towards the display module 8, the probe 5 is directly facing the center of the display screen 81 of the display module 8, and the arc surface 31 on the sliding frame 3 will press the button switch 10. When the button switch 10 is pressed, it will start the control lamp tester 6, the barcode scanner 4, and the probe 5. The barcode scanner 4 scans the information on the QR code 83, and the probe 5 obtains the data from the display module 8 for the burning process. Thus, by simply pushing the sliding frame 3, the barcode scanner 4 and the probe 5 can work simultaneously to complete the burning process, achieving the effect of saving manpower and facilitating operation.
