After years of development, the technology of LCD screen has developed from one-way to a variety of technical routes; It has also developed from low-end to high, medium and low-level LCD products. Today, Freda introduces to you the commonly used liquid crystal display technology - IPS, high-brightness, optical lamination technology, industrial capacitive touch screen technology, etc., so that you can customize the high-end LCD display products you need according to related technologies.

In many cases, glass is added to protect the surface of the LCD on devices used outdoors. But when sunlight hits the LCD surface, the reflected light causes visibility to decrease. The company has developed glass bonding products to improve the visibility of the overall module. The TFT liquid crystal module is bonded to the anti-glare glass using a resin with a similar refractive index to the glass. "This method reduces the reflection of light, reducing the reflectivity from 11.8% to 5.3%," said the manager of the liquid crystal division.

In simple terms, the basic principle of the display can work is to fill liquid crystal material between two pieces of parallel glass and change the arrangement of molecules inside the liquid crystal material through voltage to achieve the purpose of shading and transmittance to display the depth of different and well-spaced images. As long as put three color filter layer between two pieces of glass, it can display color images.

Due to the special principle and structure of liquid crystal display, attention must be paid when using and installing

Liquid crystal is an organic substance with a certain order between solid and liquid. It has the characteristics of photoelectric dynamic scattering. It has a variety of liquid crystal phase, such as cholesteric phase, various near crystal phase, nematic equality. According to the nature of different materials, all kinds of phase liquid crystal materials are mostly developed to use in flat-panel display device.

With the rapid development of liquid crystal display(TFT-LCD) technology driven by thin-film transistor TFT array, in recent years, TFT LCD has not only occupied the high-end display market such as portable notebook computers, but also challenged the desktop display with the improvement of manufacturing process and the reduction of cost.

With the rapid development of modern society, TFT LCD displays have been comprehensively entered thousands of families and more and more users love to use. But due to lots of users does not understand the TFT LCD displays very comprehensive, lots of TFT LCD displays decline in the life cycle when users do not pay attention to some details and do not maintain, and it’s also easy to cause a large number of small problems. Now we introduce a few maintenance tips of TFT LCD displays, hope to help extend the life cycle of TFT LCD displays.

The biggest problem currently plaguing the VR experience is the "vertigo."

LCD pixel is a unit to be used to calculate digital impressions, as if the same photograph was taken, digital impressions also have a continuum of shades. If you multiply the impression a few times, you will find that these contiguous colors are actually composed of many small square dots around the color.
