China 3.5 inch lcd display 320*480 ST7796 Manufacturers, Suppliers, Factory

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.

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.

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.

Conventional 5 inch display screens cannot be seen clearly under strong outdoor sunlight unless they have a brightness of 2000 lumens. To achieve this brightness, the number of high-brightness LED lights needs to be increased, which will increase power consumption and reduce battery life. Our company has successfully mass-produced a semi-transparent and semi-reflective 5 inch screen with a resolution of 800*480 and an RGB interface. It can display clearly in the sun without turning on the LED light, which reduces the power consumption of the machine and is the first choice for many outdoor electronic devices.

In order to continuously meet more customers' order demands for TFT LCD products, the company's latest purchased LCM automatic production equipment has been shipped to the company on September 25.
