Embodiment Construction

[0030] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] figure 1 A schematic structural diagram of a display device according to an embodiment of the present invention is shown.

[0032] Such as figure 1 As shown, similar to the display device in the prior art, a lower polarizing layer 2 is formed on the backlight module 1, a lower substrate 3 is formed on the lower polarizing layer 2, and a liquid crystal layer 4 is formed between the lower substrate 3 and the protective layer 5. A filter layer 6 is formed on the protective layer 5 , an upper substrate 7 is formed on the filter layer 6 , and an upper polarizing layer 8 is formed on the upper substrate 7 .

[0033] The difference between the display device according to the embodiment of the present invention and the display device in the prior art is that the filter layer 6 includes a combination of multiple groups of red filters, blue filters and ...

Abstract

The invention relates to a display device which comprises a display panel, a backlight module located below the display panel, and a driving circuit, wherein an optical filter substrate of the display panel comprises multiple groups of optical filter combinations, and each optical filter combination comprises red optical filters, blue optical filters and transparent optical filters; the backlight module comprises a white light backlight source and a green light backlight source; the driving circuit drives the white light backlight source to emit light when frames are of odd numbers to be displayed though red and blue pixels, and drives the green light backlight source to emit light when the frames are of even numbers to be displayed through transparent pixels; alternatively, the driving circuit drives the white light backlight source to emit light when the frames are of even numbers to be displayed through the red and blue pixels, and drives the green light backlight source to emit light when the frames are of odd numbers to be displayed through the transparent pixels. According to the technical scheme, under the premise that an Adobe RGB chromaticity coordinate is met, adjustment of mixing light colors and promotion of luminance are achieved at the same time.

Description
