Basic Knowledge And Selection Of LCD Liquid Crystal Display

- Jun 18, 2020-

LCD liquid crystal display is widely used in display products and is currently the most commonly used display. Understand the basic knowledge of LCD liquid crystal display, in order to better product selection. This article will analyze the basic knowledge of LCD screen from the aspects of contrast, response time, resolution, etc., and then analyze the selection from the aspect of product application.

 

Basic information of LCD screen

 

1. Electro-optical characteristics of LCD liquid crystal display: the characteristics of the relative transmittance of LCD with the change of applied signal voltage.

 

Second, the resolution

 

Resolution is also called resolution, pixel degree, etc., what we see from the display is composed of pixels. In the case of the same screen size, the larger the pixels, the finer the displayed screen content. For example, the resolution of 1366*768 means that the display screen has 1366 pixels in the horizontal direction and 768 pixels in the vertical direction.

 

3. Contrast

 

Under the condition of a certain external brightness, the ratio of the brightness of the LCD display part to the dark state; that is, the difference between the foreground and background colors;

 

Four, perspective

 

When viewing the LCD screen, you can see that the display graphics are the clearest, and the angle with the best display effect (good contrast) is called the LCD viewing angle.

 

5. Response time

 

Transmittance time from 10% to 90%, that is, the time difference between applying the driving signal and seeing the pattern you want

 

LCD screen selection

 

First, we must start from the application of the product

 

As a kind of LCD liquid crystal display, LCD color screen has a wide range of applications. Among them, commercial advertising machines basically use LCD color displays, as well as some automotive LCD displays, medical LCD displays, monitoring, security, etc. .

 

Second, from the analysis of size requirements

 

On which instrument is the LCD screen used! What size screen is needed! When choosing a model, the most important thing is also the size. The appropriate LCD screen should be selected according to the product requirements. Jushi Display mainly sells laptop screens. Misunderstandings may easily arise here. In fact, notebook screens are not only applicable to notebooks. Notebook screens can be used in many fields, as can advertising machines and pos machines.

 

Three choose from the output value of the product

 

If the LCD screen is installed on the device, this output value is relatively large. High-end product positioning, you can choose good quality display, good quality LCD screen display effect is better. As far as notebook panels are concerned, narrow bezels, high resolutions, small interfaces, IPS screens, etc. are all future trends.
