How to choose the oled display

The quality of an LCD display panel first look at it , because the panel will have a direct impact on the viewing screen , and LCD panels account for the whole cost of the 2 /3, are the main factors affecting the cost , so to choose a good LCD monitor, it must first choose the right panel . Many consumers in the purchase will be specially concerned about what kind of display panels used , and even many consumers buy when the monitor display panel will blindly believe that all liquid crystal display panel decision .

For example, many people think that the field of LCD panels Sharp screen , the Samsung screen is synonymous with good quality , while the domestic and Taiwan-based panel system is garbage , so the idea is not correct . First, we must understand the difference between LCD panel in addition to the common TN panels , MVA and PVA panels , such as the class VA , IPS panels and CPA panel , as well as the driver IC circuit , as well as polarizers, filters, polarizers , more than a dozen components of the backlight system, part of the same advantages and disadvantages of these will affect the final performance of the merits panel .

Some display manufacturers in "the only panel on " a big fuss , in order to promote their products , naturally to "meet " consumer demand responsibility . Over time , plus some " crowd know the truth ," the push waves to help out, many characteristics of the LCD panel or exaggerated or distorted, or do nothing, has tampered with the original true beyond recognition . Today , this article is intended to help consumers want to buy a monitor poke this heavy fog on the graphic lcd modules panel has a comprehensive understanding.

Do not look into the factory mode panel provenance

In simple terms , the liquid crystal panel can be seen as an intermediate between two glass substrates sandwiching a liquid crystal layer , the upper glass substrate and the color filter are combined , and the lower layer has a glass inlay on transistors . When the current changes in the electric field generated by the transistor , liquid crystal molecules resulting deflection of light in order to change the bias polarity , and then decided to use Polaroid pixel shading state .

Sounds like a relatively easy , however, because the complexity of the production process , the production line a huge investment ( the cost of a high- generation line of over 10 billion yuan ) , there are a lot of patent restrictions , coupled with the need to glass substrate ( conductive glass ) , colored filter, polarizer , backlight and other auxiliary materials alignment agent , limiting the sealing rubber and gasket material , etc. , graphic lcd display module the real production capacity of LCD panel manufacturers few.
