Of tn va ips lcd panel differences - China 4 aa usb charger - deep cycle battery charger

In daily life, we can not do without LCD display, LCD TV , Phone / digital products based on these to the screen output application IT Products, which make our lives colorful and support these products based think we all understand, and LCD panel LCD products is the highest point of the pyramid chain, it can determine those around us towards the development of video display devices to we are most familiar liquid crystal display, the panel's Chen to take the product 80%, the rest is just the look we can see the mold and the internal A / D circuit module and power supply circuits, monitors product innovation and LCD panel prices still have to go around, since it is so important, then we introduce today's gave several different types of LCD panel differences.

Now on the market for LCD panels used in LCD is divided into three categories, including TN, IPS, VA (MVA and PVA) panel, which users access the most TN panel products, it has a cost advantage as a market some of the absolute majority, while the other two panels of the products also have their own characteristics, it is necessary to find out.

TN panels are soft screen, and lightly water stripe program will be similar, TN panel has the advantage of lower series the output grayscale, liquid crystal molecules tilt speed, response time, easy to raise, TN panels can only display 0 the three primary colors to 252 gray scale, and finally get the number of information is 16.2M color display color, so why when we purchase displays, information received can display 16.7M colors are, it is only through hardware technology to achieve jitter effect, compared with 8Bit Panel naturally can not in the same category. But the point of view in, TN panels have wide viewing angle compensation film used to increase the viewing angle, although it sounds TN panel shortcomings, but the compensation through a series of technology coupled with cost advantage or make it popular.

VA panels are now more high-end LCD panel type application, are wide viewing angle panel. And the TN panel compared to, 8bit panel can provide 16.7M colors and great viewing angle is the capital of such high-end positioning panel, but the prices are also a number of relatively expensive TN panel. VA panels can be divided into classes led by the Fujitsu MVA panel and developed by Samsung PVA panels, the latter of which is a continuation and improvement of the former. VA type panel front (face) the highest contrast, screen uniformity, but not good enough, often the color shift occurs. Sharp text is its trump card, a high contrast black and white. Samsung F2370 is used by VA panels, used in this display will be a very good friend of the evaluation.

IPS panel is the biggest characteristic of a hard screen, if that is the direction of left and the Yulin Zhuang pixels, with a hard screen, then can determine is the IPS panel. Its molecular structure is strong and stable, will not face external forces affecting the screen image distortion and color with touch function is very suitable for public display. IPS screens greatly enhance the contrast and viewing angle, increasing the reduction degree of color, high quality natural occupy high status.

These three LCD panels contrast clearer, TN panels are low end and VA, IPS panels are high end products, TN panels are 6Bit the panel can only display of 64 * 64 * 64 gray, from the structure up only display 16.2M colors, while the VA and IPS panels are 8Bit, not acquired through technical compensation reached 256 (2 to the 8th power) level grayscale display, which is equal to 256 * 256 * 256, 16.7M colors, may be Some people think that since the TN panel by dithering technology has reached a real color effects, but which would be bad design to the color problem, the principle of vibration technology is let you see the yellow, and then quickly you see the blue, this mixed out of the visual is a different color, this subtle change of course we can not tell, but when frequent dynamic images, the color of purity will be affected, deviate from a certain angle the picture effect when there are major changes , this is also the wide viewing angle panel admired reasons.

TN panel above the vertical angle of recession is very obvious color

Consumers now attach great importance to the game, Video The picture is outstanding, increasingly rich colors and dynamic visual effects to our great enjoyment, TN panel monitor can only be said to meet the popular needs, a real professional who is definitely not easy its defects. TN Board of the greatest advantages is the relatively low cost, which also contributed to the rapid popularization of LCD displays, while the VA and IPS panel board products for the past more fields, but now the reason to discuss these types of LCD panels also because of the pace of high-end panel of the poor start, and the recent launch of the IPS AOC screen display iF22, iF23 around 1,300 yuan in the early Dell 2209WA listing is no longer expensive. The VA representative is well-known screen Samsung F2380.
