What is the difference between side light type LED and vertical type, backlit type? Which is better? No pictures?
Now there are two ways to do LED backlight: metering and direct.Metering is to place the LED on the side of the light guide panel. After the LED is lit, the light is uniformly illuminated behind the LCD panel by the light guide panel, so that the image displayed on the front of the LCD panel can be seen;
The difference between direct and metering is that the LED is placed evenly behind the LCD panel, and when the light is LED, the display image is seen on the front of the LCD panel.
Which is better, each has its own characteristics. Light type light through the light guide plate to transfer, but need less LED, can also be thin; and backlit is a new technology, it does not need the light guide, but need LED quantity, also facilitate the backlight of LED makes the control more carefully, the so-called "smart backlight control"
