Embodiment
In order more to be expressly understood technology contents of the present invention, at first introduce the principle of work of LCD display:
The LCD device is a light by backlight emission during by polaroid and liquid crystal cell, the device of control projection intensity recognition image.The brightness by liquid crystal cell (transmitance of LCD screen) and color film CF light quantity (transmitance of CF) and backlight is depended in the brightness of LCD just.There are following three kinds so improve the way of LCD brightness usually:
(1) improves back light source brightness
(2) improve the TFT aperture ratio of pixels
(3) brightness of raising all material
Use the side lamp formula light source of light guide plate, suppose that the light guide plate optical efficiency is 100%, it loses 40% in light guide plate, by polaroid loss 36% down, by liquid crystal cell loss 18% and surface reflection loss 1%, important accessory and brightness source that backlight shows as LCD, extremely important concerning improving liquid crystal display brightness, therefore, people attempt multiple mode and remove to improve the LCD display brightness from the backlight aspect, at first from lamp source angle, can increase the fluorescent tube number, increase the lamp source power, but all can cause power consumption big, so all the time, puzzlement people's LCD demonstration problem is not well solved, and because the consideration of aspects such as cost, to (2), (3) plant and to improve way and do not have great practical value and meaning.
The following examples will be elaborated to method of the present invention.
