What is the difference between LPL panel and TN panel? LPL is a panel manufacturer, and lpl is the general term for all panels produced by the joint venture between LG and Philips. There are many types of LPL panels: TN is one of the panel types. Here are the types of LPL panels: va-type: va-type liquid crystal panels are widely used in current display products, and are used in high-end products. 16.7m color (8bit panel) and large viewing angle are its most obvious technical features. At present, va-type panels are divided into Two types: mva and pva. mva type: full name (mulTI-domain verTIcal alignment), is a multi-quadrant vertical alignment technology. It uses protrusions to make the liquid crystal static, not a traditional upright type, but a certain angle of static; when a voltage is applied to change the liquid crystal molecules to a level to let the backlight pass through, it is faster, so that the display time can be greatly reduced Also because the protrusions change the alignment of the liquid crystal molecules, the viewing angle is wider. The increase in viewing angle can reach more than 160 degrees, and the response time is shortened to less than 20ms. PVA type: It is a panel type introduced by Samsung, which is a vertical image adjustment technology, which directly changes the structure of the liquid crystal cell, so that the display performance is greatly improved and the brightness output and contrast ratio superior to mva can be obtained. In addition, on the basis of these two types, two types of improved s-pva and p-mva panels have been extended. The technical development is more upward, the viewing angle can reach 170 degrees, and the response time is controlled within 20 milliseconds ( Using overdrive speed up to 8ms gtg), and the contrast can easily exceed the high level of 700: 1, most of Samsung's products are pva LCD panels. ips type: ips type liquid crystal panel has the advantages of large viewing angle, delicate colors, etc. It looks more transparent. This is also a method to identify ips type liquid crystal panel. Many philips LCD displays use ips type panel. The s-ips is the second generation of ips technology, which has introduced some new technologies to improve the grayscale reversal phenomenon of the ips mode at certain specific angles. The independent panel manufacturers of LG and Philips are also LCD panels with ips as the technical characteristics. tn type: This type of LCD panel is used in entry-level and mid-range products. It is affordable and inexpensive, and is used by many manufacturers. Technically, compared with the first two types of LCD panels, the technical performance is slightly inferior, it can not display 16.7m bright colors, only 16.7m colors (6bit panel) but the response time is easy to improve. The viewing angle is also subject to certain restrictions, the viewing angle will not exceed 160 degrees. Most products on the market generally within 8ms response time are using tn LCD panels.
