June 2, 2010... LG Display unveiled its LCD panel which uses quantum dot-based LEDs as the backlight source at SID 2010, according to a Tech-On! article. The size of the prototype screen's diagonal dimension is 3.2 inches. The pixel count, pixel pitch and luminance of the LCD panel are 480 x 800, 0.087mm and 450cd/m2, respectively.

The LCD panel's color gamut was expanded by 30 percent using the quantum dot-based LEDs. When a quantum-dot LED or a conventional LED is used for a backlight source, it can expand the color gamut of the LCD panel. The colorimetric purity of a quantum-dot LED is reportedly higher than that of a normal LED.

Generally, expanding the color gamut of an LCD panel with a normal pixel structure (RGB colors) even with LEDs requires and increase in power consumption. However when quantum-dot LEDs with a high colorimetric purity are used as a backlight source the color gamut can be expanded without requiring an increase in power consumption.
