Liquid crystal injection and sealing process

LCD is a display made by using the characteristics of liquid crystal. As the name implies, we first need to prepare a glass box containing liquid crystal materials. Pouring liquid crystal into the liq

The influence of LCD screen brightness on product temperature

We all know that temperature is one of the most important factors for the normal operation of LCD screens. This chapter will reveal the temperature change rules of screens with different brightness wh

What are the touch technologies for LCD capacitive touch screens? - In-Cell/ On-Cell/ OGS

We already know that touch screens are divided into capacitive screens and resistive screens. In the past, LCD and touch screens were produced separately and could be assembled together using frame la

What is touch screen G+G, G+P, G+F?

The capacitive screen is mainly composed of two parts: the lower sensor glass layer and the upper cover. There are two structures of capacitive screens on the market: one is the sensor glass + tempere

Detection method of four-wire resistive touch display

All touch screens can detect when a touch occurs by using a weak pull-up resistor to pull one layer up and a strong pull-down resistor to pull the other layer down. If the measured voltage of the pull

Working principle of twisted nematic liquid crystal display (TN-LCD)

The liquid crystal display devices used in common watches, digital meters, electronic clocks and most calculators are TN-type devices.<br/>?? Generally speaking, as long as the liqui

Which is better, positive mode or negative mode for LCD screens?

We already know that the modes of LCD screens include TN, STN, FSTN, and VA, and their effects on the screen are different. In addition, there are also positive and negative modes in the same mode. Th
