What's the difference between IPS, TN, PVA and WLED?

1. IPS LCD: IPS LCD has strong backlight effect.
it looks transparent.
.
2. TN LCD: TN LCD has fine color.
enhances brightness output and contrast.
.
3. PVA LCD: PVA LCD has high color saturation.
.
4 WLED LCDs: WLED LCDs have poor color saturation.
.
2. Different technologies.
1. IPS LCDs: IPS LCDs use LCD technology.
.
2. TN LCDs: TN LCDs use multi quadrant vertical alignment technology.
.
3. PVA LCDs: PVA LCDs use image vertical adjustment technology.
this technology directly changes the structure of LCD cells and greatly improves the display efficiency.
.
4 WLED LCD: WLED LCD is white LED.
there is no LCD technology.
.
3. Different applications.
1. IPS LCD: IPS LCD is widely used in display products.
it is used in high-end products.
.
2. TN LCD: TN LCD has lower cost.
it is used in entrance and middle end products.
.
3 PVA LCD: PVA LCD is widely used in display products.
used in high-end products.
.
4. WLED LCD: WLED LCD has been gradually replaced.

1. VA type: VA type LCD panel is widely used in the current display products.
in the high-end products, 16.7M color (8bit panel) and large viewing angle are its most obvious technical features. At present, VA type LCD panel is divided into two types: MVA, LCD panel and LCD panel PVA.
.
.
2. MVA type: fully known as (multi domain vertical alignment).
is a multi quadrant vertical alignment technology.
it uses the protrusion to make the liquid crystal static, not the traditional vertical type.
it is inclined to a certain angle; When the applied voltage changes the liquid crystal molecules to the horizontal to let the backlight pass, it will be faster.
.
.
3. PVA type: a panel type launched by Samsung.
it is a vertical image adjustment technology, which directly changes the structure of the liquid crystal cell, In addition, two types of improved S-PVA and p-mva panels are developed on the basis of these two types.
.
4. IPS type: IPS type LCD panel has the advantages of large viewing angle and fine color.
it looks transparent, which is also a method to identify IPS type LCD panel, Many liquid crystal displays in Philips use IPS type panels.
.
5. TN type: this type of liquid crystal panel is used in entry-level and mid-range products.
it is affordable and cheap, and has been selected by many manufacturers.
.
6. Liquid crystal display (short for liquid crystal display).
.
67. The structure of LCD is to place a liquid crystal cell between two parallel glass substrates.
TFT (thin film transistor) is set on the lower glass substrate, and color filter is set on the upper glass substrate. The rotation direction of liquid crystal molecules is controlled by the change of signal and voltage on the TFT, So as to control the polarized light emission of each pixel and achieve the purpose of display.
.
8. Now LCD has replaced CRT as the mainstream.
the price has also dropped a lot, and has been fully popularized.
