Embodiment
For making the technical problem to be solved in the present invention, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
First the present invention provides a kind of display panel, and structure as shown in Figure 1, comprises color rete 101, the sub-pix 1011 that described color rete comprises different colours and the optical filter 1012 of answering with sub-pix Color pair; Described sub-pix 1011 produces the light of corresponding color under the irradiation of blue light; Described optical filter 1012 is arranged on the side of corresponding sub-pix 1011 away from blue light incident direction; Described color rete also comprises blue-light-emitting unit 1013, and described blue-light-emitting unit 1013 is gap structure.
As can be seen from above, the sub-pix that the color rete of display panel of the present invention has different colours and the optical filter of answering with sub-pix Color pair, thus the blue color filter removed in existing display panel, blue region does not cover quanta point material, and blue region does not arrange the direct transmitted light blue light of optical filter, thus greatly can improve the utilization factor of light source, obtain more highly purified coloured light simultaneously, realize high colour gamut and the low-power consumption of colored display.
Because the blue light through sub-pix can not be converted to color corresponding to described sub-pix completely, in the blue light of this sub-pix, still some blue light can be gone out by sub-pix transmission, therefore, at sub-pix, the side of blue light incident direction is provided with the optical filter of answering with sub-pix Color pair, this optical filter only allows the light identical with corresponding sub-pix color to pass through, and the blue light filtering will projected by sub-pix.
In most cases, the sub-pix of described different colours comprises red sub-pixel, green sub-pixels.The optical filter corresponding with red sub-pixel is Red lightscreening plate, only allow red light through, the light of other color cannot pass through; The optical filter corresponding with green sub-pixels is green color filter, only allow green light through, the light of other color cannot pass through.Can not only colour gamut be improved like this, can also prevent the light between neighboring sub-pixel from influencing each other.
