LCD screen itself has problems. If it is indeed the screen itself that is at fault after testing with relevant instruments, in addition to replacing a new LCD screen, the device-related software should be debugged and optimized so that the screen can work with the motherboard's CPU. The best way is to increase the OSC frequency of the IC and see how the LCD screen flickers. Of course, if the TFT LCD screen has separate row and column drivers, you can also adjust it by setting the driver chip.

Backlighting is used in small, light, flat-panel liquid crystal displays (LCDs) and other electronic devices that require backlighting, including handheld devices as small as the palm of your hand, and large-screen TVs. The goals of backlight design include low power consumption, ultra-thin, high brightness, uniform brightness, large area, and control of different width and narrow viewing angles. To achieve these challenging design goals with controlled cost and rapid implementation, computer-aided optical design tools must be used for design. This article introduces the characteristics of LightTools optical design and analysis software from ORA Company in the United States, which can be used to develop the most advanced backlight design applications today.

If customers encounter screen display problems and want to check whether they are caused by flexible cables, they can check from the following aspects, including appearance, material, process, and functional testing to distinguish: It should be noted that the display screen may not display normally sometimes not because of the flexible cable itself, but because of interface oxidation or motherboard problems, but the flexible cable is the easiest to check as a connecting component. Therefore, when distinguishing problems, multiple factors should be considered comprehensively, and you cannot just look at one point.

In order to meet the increasing number of new orders, Shenzhen Hongjia Technology added a fully automatic TFT screen production equipment to the factory on November 25, 2024, including one-stop feeding such as glass cleaning, COG bonding, FOG bonding, backlight assembly, etc. before production.
