The interpretation of LCD keywords only gives the basic concept. If you want to know more about the source hierarchy of LCD features. Then, this article will give you what you want. Here, in addition to the in-depth analysis of each characteristic, we will also tell you the reason for uneven brightness or color bias LCD, LCD contrast Settings error, what caused the effect of LCD distortion in the optimal resolution. Our country to the LCD product bright spot and the bad spot stipulation and so on with the application and the consumption-related knowledge closely. LCD performance:

1. Electro-optical characteristics of LCD (liquid crystal display) 

The characteristics of the relative transmittance of LCD with the change of external signal voltage.

2. Threshold voltage V10 and saturation voltage V90

Threshold voltage: the voltage when the brightness of the LCD display reaches 10% of the maximum variation; Generally speaking, the LCD can just see the display voltage;

Saturation voltage: the voltage when the brightness of the LCD display reaches 90% of the large change of the density; Generally speaking, the LCD just reaches the clearest display locust voltage;

3. Contrast

The brightness ratio of the bright state and the dark state of the LCD display under the condition that the brightness of the outside is certain; Namely the difference between foreground and background color;

4. Angle

When viewing the LCD screen, you can see the most clear display graphics, display the best (good contrast) Angle is called the LCD perspective,

5. Response time

The transmittance goes from 10% to 90% of the time, the time between applying the drive signal and seeing the shape you want
