La plus grande différence entre l'écran LCD souligné et l'écran LCD ordinaire

The brightness of écran LCD is determined by the brightness of backlight, there are many ways to improve the brightness of backlight; according to whether or not to increase the power consumption can be roughly divided into three categories:

1, directly increase the power consumption to improve the brightness; the second is to increase the number of LED lamps; the second is to increase the current of LED lamps; the advantages of these two are to improve the brightness directly; the disadvantage is that the power consumption increases and the heating value increases.

2, the conventional design of increasing brightness without increasing power consumption, using film materials with higher optical effect, such as bright light enhancement, high transmittance diffusion, high reflectivity reflection, or the application of large chip LED lamp, can improve brightness at the same power consumption; the advantage is that it can further improve brightness, and the performance price is higher, and the power consumption is zero; the disadvantage is that the cost is obviously increased.

3, the unique system scheme does not increase the power consumption to improve the brightness, applies the innovative prism light guide plate technology to increase the brightness by 30%; applies DBEF film material to increase the brightness by 25%; improves the contact between the LED lamp and the light guide plate to increase the brightness by 10%; the advantage is that the power consumption increases zero and can increase the brightness by about 80%; the disadvantage is that the cost is relatively high.
