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.

​The primary part of an LCD display is an LCD panel, or liquid crystal display. It is a flat panel with two glass panels layered on top of small liquid crystal cells. The crystals align and alter the amount of light that passes through them when an electric current is applied, creating an image that can be seen.

​An LCD temperature display is a kind of digital temperature display that shows the current temperature using a Liquid Crystal Display (LCD). It is frequently found in gadgets like air conditioners, weather stations, and thermometers.

The material design of underwater touch screens must focus on the three core goals of "waterproof and water-proof, corrosion-resistant and non-failure, and touch without misjudgment". The super-hydrophobic cover layer is used to reduce water interference, corrosion-resistant conductive materials replace traditional ITO, and precision sealing structures block water penetration. In addition, the appropriate material combination is selected in combination with scene requirements (such as consumer grade/industrial grade/deep sea grade).

Usually, touchable LCD screens are capacitive screens, and the positioning method of the touch screen is through the electric field. Therefore, when static electricity and discharge occur, the LCD touch screen will have a "drift" screen effect, that is, the click position is offset from the actual response position.

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.
