China 3.5 inch Sunlight-readable display 480*640 Manufacturers, Suppliers, Factory

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.

Many customers have reported that touchscreens easily separate from the casing in extremely cold or hot environments. This is usually due to the use of ordinary double-sided tape to fix the touchscreen. Shenzhen Hongjia Technology engineers, through extensive research, have found that using VHB double-sided tape around the edges of the touchscreen cover glass solves this problem of screen separation from the casing. In the assembly of high-end touchscreens (especially for demanding industrial, automotive, outdoor, and high-end consumer electronics products), using 3M VHB double-sided tape to fix the cover glass has become a "gold standard" process. Its advantages far outweigh traditional liquid adhesives or ordinary double-sided tapes.

We serve many Fortune 500 companies and provide 36 months of after-sales service. We have a professional display brightness measurement instrument BM-7. The display brightness can reach 2000 lumens, meeting the requirements of clear readability in the sun. It is widely used in drone remote controls, handheld devices, aerospace equipment and other products. Customers are welcome to email us for consultation.

Another advantage of using a 3.4-inch round TFT screen is that it is compatible with both RGB and MIPI interfaces. RGB interfaces are commonly used in consumer electronics, while MIPI interfaces are popular in mobile devices. Shenzhen Hongjia Technology produces 3.4-inch round TFT screens that can support RGB interface support 16/18/24 bits; also supports MIPI interface support 2/3/4 channels. This compatibility allows for easy integration with a variety of products, making it a versatile choice for many different applications.

Some customers are still not very clear about the resolution of the display screen. We will explain it here. The resolution of the LCD screen refers to the number of pixels of the LCD screen, that is, the number of dot matrix, which is usually the number of pixels in the horizontal direction multiplied by the number of pixels in the vertical direction. Under the same LCD screen size, the higher the resolution dot matrix, the clearer and more delicate the display image effect is.
