China 3.99 inch bar tft touch screen Manufacturers, Suppliers, Factory

Generally, customers think that LCD screen flower screen is a hardware problem, but in fact, software driver problems may also cause it. Customers need to be guided to check step by step to find the problem.

Compared with parallel ports, MIPI interface modules have the advantages of fast speed, large amount of data transmission, low power consumption, and good anti-interference. They are increasingly favored by customers and are growing rapidly.

3.99-inch long strip LCD screen with a resolution of 400*960, supporting RGB/MIPI interfaces and featuring a capacitive touchscreen, is currently widely used in the market. Its aspect ratio is well-suited for home appliances, smart home devices, and consumer electronics. The 3.99-inch long strip screen uses common driver ICs, making debugging simple. Another core advantage lies in its unique physical shape and the fine display effect brought by its high resolution.

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.

Our company has developed a 4.3-inch vertical screen and has been mass-produced. The display supports MCU interface 8BIT and 16BIT. The screen driver IC has video memory, which can realize the flip display of the screen.

First, it should be clear that the main type of radiation produced by LCD monitors is low-frequency electromagnetic radiation, and its radiation level is far below international safety standards. Compared with the old cathode ray tube (CRT) monitors, LCDs have much less radiation. Therefore, the impact of LCD devices on the human body is very limited. However, there are ways to reduce the impact of this radiation. In this article, we will explore some effective ways to reduce LCD screen radiation.
