What principle is leaked

LCD light leakage between the main screen is the agreement with the LCD lead frame does not close out the light transmittance of the lamp , this is a common problem in the LCD TV ,graphic lcd 128x64 or from a certain angle, a phenomenon can not be avoided , but is not the same extent .

LCD TV leaked the main reason there are two , the first is the question of the panel, when the panel is not good quality, or means of transport accidents , resulting in curved panels , so there will be a serious light leakage problem , if it is checked out at the factory in this case, the factory will be banned . Another is when assembled , convergence between the LCD panel does not close the border with the cause slight light leakage. But in general it is difficult to see out the naked eye , and only in total darkness environmental inspection to clearly see the light leakage.

What is the principle of light leakage is it ? We mentioned earlier , is due to problems caused by convergence , where the allowed range , is a normal phenomenon , but does not affect the life of the TV leaked , response time, brightness and other parameters. Countries have enacted regulations under the black case, leaked ≤ 4cd / standards.

We buy products TFT LCD Display television, a major concern dead pixels, bright spots , dark spots, light leakage and other factors, while the red , green and blue are the three basic color television , which is the main measure of television color parameters, we tested when the LCD TV is mainly used red, green, blue, white , and black colors to examine the quality of the product
