[0002] With the continuous development of program code memory, one-time programmable (OTP) is widely used in electronic devices due to its low cost advantage. In the display screen industry, OTP is a key hardware technology.

[0044] The OTP programming device for the display screen provided in the above embodiment operates as follows:

[0045] (1) The first linear drive component 3 drives the first burning platform 1 to the loading station 300. The operator loads the first display screen to be burned onto the first burning platform 1, and uses the first pressing hook 14 to press and fix the first display screen onto the first test carrier plate 13, and electrically connects the first display screen to the first burning component 12.

[0046] (2) After the first programming platform 1 is loaded, the first linear drive component 3 drives the first programming platform 1 to the programming dark chamber 200. The first programming component 12 performs OTP programming on the first display screen, and the optical probe component 5 detects the programmed first display screen. When the first programming platform 1 performs OTP programming on the first display screen, the second linear drive component 4 drives the second programming platform 2 to the corresponding position of the loading station 300, and the lifting drive component 2a drives the second programming platform 2 to rise to the loading station 300. The operator loads the second display screen to be programmed onto the second programming platform 2, and the second display screen is pressed and fixed onto the second test carrier plate 23 by the second pressing hook 24, and the second display screen is electrically connected to the second programming component 22. After the loading is completed, the lifting drive component 2a drives the second programming platform 2 to fall. Then, the second linear drive component 4 drives the second programming platform 2 to the bottom of the programming dark chamber 200.

[0047] (3) After the first programming platform 1 completes the OTP programming of the first display screen, the first linear drive component 3 exits from the programming dark chamber 200, and the lifting drive component 2a drives the second programming platform 2 to rise to the programming dark chamber 200. The second programming component 22 then performs OTP programming on the second display screen, and the optical probe component 5 inspects the programmed second display screen. At this time, the first linear drive component 3 drives the first programming platform 1 to the loading station 300 for unloading, and, referring to the process in step (1), loads another display screen to be programmed.

[0048] (4) After the second programming platform 2 completes the OTP programming of the second display screen, the lifting drive component 2a drives the second programming platform 2 to descend and exit from the programming dark chamber 200, and then repeats the operation process of step (2). In this cycle, the first programming platform 1 and the second programming platform 2 alternately switch between the programming dark chamber 200 and the loading station 300 to perform OTP programming on the display screen respectively.

[0049] In summary, the OTP programming device for a display screen provided by this utility model embodiment includes a first programming platform and a second programming platform capable of performing OTP programming operations respectively. The first programming platform and the second programming platform can be driven independently, alternating between the programming darkroom and the loading station: when the first programming platform completes loading and is driven to the programming darkroom for OTP programming, the second programming platform is driven to the loading station for loading; when the first programming platform completes the programming operation, the second programming platform is driven to the programming darkroom for OTP programming, while the first programming platform is driven to the loading station for loading and unloading, and so on in a cyclical operation, thereby reducing the equipment's waiting time and improving production efficiency.
