Problems solved by technology

Among them, the red pixel area and the green pixel area are filled with quantum dot material, the quantum dot material allows users to receive red light or green light at various angles, while the blue pixel area needs to pass through the blue light source, usually filled with transparent The material doesn't even fill, which causes the problem of viewing angle shift in the blue pixel area

[0031] see figure 2 , the blue filter film 130 is used to weaken the intensity of the outgoing blue light, so that the blue light at a certain brightness is not easy to pass through, and the brightness of the blue light above a certain brightness is weakened after passing through. In this embodiment, by adjusting the thickness h1 of the first filter area 131 to be different from the thickness h2 of the second filter area 132, the brightness of the blue light weakened by the first filter area 131 is different from that of the second filter area 132. The brightness of the blue light weakened by the light area 132 is different, so that the display brightness of the first sub-pixel area 122 and the display brightness of the second sub-pixel area 123 are different, thereby reducing the problem of blue light viewing angle shift in the blue pixel area 121 .

[0032] Optionally, the materials of the first filter area 131 and the second filter area 132 can be the same, and the blue fi...

[0036] In this embodiment, by adjusting the ratio of the area of ​​the first sub-pixel area 122 to the area of ​​the second sub-pixel area 123, the display brightness at the first sub-pixel area 122 is the same as that at the second sub-pixel area 123. The display luminances are different, thereby reducing the problem that the blue light in the blue pixel area 121 has a biased viewing angle.

[0037] Optionally, the ratio of the area of ​​the first sub-pixel region 122 to the area of ​​the second sub-pixel region 123 is 1:4˜4:1. When the area of ​​the sub-pixel area of ​​the blue pixel area 121 is too large, the brightness of the blue light transmitted by the sub-pixel area is too large, and the effect of weakening the blue light is weak. When the area of ​​the sub-pixel area of ​​the blue pixel area 121 is too small, the brightness of the blue light transmitted by the sub-pixel area is too high, which affects the display quality of the display panel 100 .

no. 3 example

[0040] The display panel 100 also includes a first data line and a second data line (not shown). The first sub-pixel area 122 is electrically connected to the first data line, the second sub-pixel area 123 is electrically connected to the second data line, and the first data line and the second data line output different data signals. Then, the first sub-pixel region 122 and the second sub-pixel region 123 input different data signals, so that the first sub-pixel region 122 and the second sub-pixel region 123 have different grayscales, thereby The display luminance at the first sub-pixel area 122 is different from the display luminance at the second sub-pixel area 123 , thereby reducing the problem of the blue light viewing angle shift in the blue pixel area 121 .

[0041] In this application, the above-mentioned technical means of the first embodiment, the second embodiment and the third embodiment can be used in combination, that is, according to the area ratio of the first...

Abstract

The invention provides a display panel. The display panel includes a backlight source, a color filter layer and a blue filtermenbrane which are sequentially arranged in a stacked mode. The color filter layer includes a blue pixel area, the blue pixel area includes a first sub-pixel area and a second sub-pixel area, the blue filter membrane is provided with a first light filtering area and a second light filtering area, the first filtering area is arranged opposite to the first sub-pixel area, and the second filtering area is arranged opposite to the second sub-pixel area. A ray radiated by the backlight source penetrates through the first sub-pixel area and the first light filtering area and becomes a first ray, a ray radiated by the backlight source penetrates through the second sub-pixel area and the second light filtering area and becomes a second ray, and the light intensity of the first ray is different from that of the second ray. The invention further provides a mobile terminal. The display panel and the mobile terminal solve the problem of visual-angle color errors occurring in the blue pixel area.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a display panel and a display device. Background technique [0002] The color of the liquid crystal display is realized by means of a color filter (CF, color filter). However, traditional color filters have the disadvantages of poor utilization of light and low transmittance, and the transmission peak of traditional color-resist materials is wide, the color density is limited, and it is difficult to achieve a wide color gamut, which can no longer satisfy users. Requirements for display quality. Quantum dots (Quantum Dots, QDs) are spherical semiconductor nanoparticles composed of II-VI or III-V elements, with a particle size generally ranging from a few nanometers to tens of nanometers. Due to the small half-width of quantum dot materials and the luminescent color can be easily adjusted by the size, structure or composition of quantum dot materials, the applicati...
