What is the LCD panel

The LCD panel can determine to a large extent the brightness of the liquid crystal display, contrast, color, visual angle, the rapid development of LCD panels and LCD panels have a very close relationship, its output, quality and market environment, and many other factors are related to the liquid crystal display of its own quality, price and market trend, Because the cost of a flat panel monitor is about 80% of its costs are concentrated on the panels.

Type of LCD panel:

VA type: VA-type LCD panel in the current display products are widely used in the high-end products, 16.7M color (8bit panel) and large visual angle is its most obvious technical features, the current VA-type panels are divided into two kinds: MVA, PVA.

MVA type: All known as (multi-domain Vertical alignment), it is a kind of multi quadrant vertical distribution technology. It is the use of the protrusion to make the liquid crystal static is not a traditional upright type, instead, it tends to be stationary at a certain angle. When the voltage is applied, the liquid crystal molecule is changed to a level so that the backlight is passed faster, which can shorten the display time greatly, and also because the highlight changes the liquid crystal molecule to match, so that the angle of view is wider. The increase in the angle of view can reach more than 160 degrees, the reaction time shortened to less than 20ms.

PVA Type: Samsung introduced a type of panel, is a vertical image adjustment technology, the technology directly changes the structure of liquid crystal units, so that the display performance significantly increased to achieve a greater than MVA brightness output and contrast. In addition, on the basis of these two types of improved S-PVA and P-MVA two types of panels, in the technical development of more trend, visual angle of up to 170 degrees, response time is controlled within 20 milliseconds (using overdrive acceleration to 8ms GTG), and contrast can easily over 700 : 1 high standard, most products of Samsung self-produced brand are PVA LCD panel.

IPS type: IPs LCD panel has a visual angle, color delicate and so on, looks more transparent, this is a way to identify the IPs LCD panel, Philips many LCD monitors are using IPS-type panel. While S-ips is the second-generation IPs technology, it introduces some new techniques to improve the gray-scale reversal of IPs mode at some specific angles. LG and Philips Independent panel manufacturers are also the introduction of IPs for the technical features of the LCD panel.

TN Type: This type of LCD panel applied to the entry-level and midrange products, affordable and inexpensive, is selected by many manufacturers. Technically, compared with the first two types of LCD panel in the technical performance of a little less, it can not show 16.7M gorgeous color, only to achieve 16.7M color (6bit panel) But the response time is easy to improve. Visual angle is also subject to a certain limit, the visual angle will not exceed 160 degrees. Now in the market generally in the 8ms response time products are mostly used in the TN LCD panel.
