Problems solved by technology
The current mainstream LCD liquid crystal technology has a light utilization rate of less than 6% due to polarizers, color filters, and aperture ratios. The optical path loss of light in DLP technology is also relatively large. The problem of OLED also exists in the light efficiency of electronic excitation. QLED display technology belongs to photoluminescence technology, which should have better energy-saving effect in theory
The LED display cannot achieve high gray scale and high color gamut at low brightness. Reducing the brightness of the LED display is at the expense of the gray scale and color gamut (or number of colors) of the LED display. Low brightness LED The display screen will have defects such as moiré fringes, LED lights flickering, reddish color, and narrow color gamut. However, high-brightness LED display screens will cause glare effects when used indoors, and human eyes will feel uncomfortable after watching for dozens of minutes. , so, LED display is not suitable for indoor environment with low brightness
It is not that LED lamps are not energy-saving, but that high-brightness LED lamps consume a lot of energy, but in order to meet the color gamut requirements, high-brightness LED lamps have to be used for display screens.
