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 recent years, people have become increasingly demanding of the aesthetics of home appliances. The traditional monochrome LCD screens with square buttons no longer meet the needs of consumers. Therefore, the round button color LCD screen has emerged to cater to the needs of consumers. This article will introduce the characteristics of the round button color LCD screen, its contribution to home appliance aesthetics, and why it is a high cost-effective solution.

Ordinary LCD screens use CCFL light sources, that is, cold-cathode fluorescent lamps (similar to the scanning lamps in the copy), with one on each side of the screen and a backlight on the back of the display, which is composed of fluorescent substances. The light sources on both sides can be evenly distributed on the back of the entire screen, so that the entire screen can be evenly illuminated. However, due to technical limitations, the brightness of such a display is not completely uniform, but it is difficult to find it. At the same time, the lamp also has a certain lifespan, and it will turn yellow after a long time.

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.
