1, the arrangement of liquid crystal molecules.
Va screen: VA screen can be roughly understood as between IPS and TN screen, and liquid crystal molecules are twisted at a certain angle instead of perpendicular.
Tn screen: When displaying white, TN screen guides light through spiral liquid crystal molecules in the horizontal direction, while when displaying black, liquid crystal molecules change from the horizontal direction to the vertical direction, resulting in the light cannot be smoothly guided through, so the English name of TN screen is twisted.
2. characteristics.
Va screen: The front (front) contrast is the highest, but the screen uniformity is not good enough, and color cast often occurs, but the black-and-white contrast is quite high, but the viewing angle is relatively narrow, and there will be different degrees of color cast according to the viewing angle.
Tn screen: It is the most widely used entry-level liquid crystal panel with low production cost, and is widely used in mainstream low-end liquid crystal displays on the market at present. Quick response, low radiation level, more suitable for games.
3. color.
Va screen: 8-8bit panel can provide 16.7M color and large viewing angle, which is the capital for this kind of panel to locate high-end.
Tn panel: It belongs to 6Bit panel. The TN panel of the early 6bit driver IC can only display 64 colors of red/green/blue, and the maximum actual color is only 262.438+044.
4. perspective.
Va screen: VA screen is a wide viewing angle screen, and most of the publicity can reach the viewing angle of 178 degrees, close to 180 degrees, which can basically be achieved from the actual perception.
Tn screen: The viewing angle can only reach 160, and the liquid crystal molecules twisted inward in the vertical direction make the light exit perpendicular to the screen, so the best viewing effect can only be achieved when the human eyes are facing the screen, and the screen will have obvious color cast.
5. price.
Va panel: VA panel is a panel type widely used in high-end LCD, belonging to wide viewing angle panel. Compared with TN panel, 8-8bit panel can provide 16.7M color and large viewing angle, which is the high-end capital of this kind of panel, but the price is also more expensive than TN panel.
Tn screen: A low-cost and most widely used entry-level LCD panel, which is widely used in mainstream low-end LCD in the market.
