Description
Technical Field
The present invention relates to the field of display technologies, and in particular, to a display panel and a display device.
Background
As the liquid crystal display industry is gradually mature, liquid crystal display products are rapidly being applied to various fields of society. At present, in the liquid crystal display panel in the industry, the color filter in the pigment color filter is adopted to filter out the spectrums of red, green and blue wave bands in the backlight spectrum to realize color display, and in the liquid crystal display panel, because the color filter in a single sub-pixel only extracts light of a certain wave band, light of other wave bands needs to be filtered out, and the transmittance is lower, the energy loss is more. The quantum dot material has small particle size, reaches the nanometer level, has high absorption efficiency which can reach more than 90 percent, so the quantum dot material is placed in the liquid crystal display panel for filtering light, and the light-emitting efficiency of the liquid crystal module can be improved.
As shown in fig. 1, when the liquid crystal display panel adopts quantum dots to filter light, the backlight source adopts blue backlight, a red quantum dot conversion unit is arranged in a red sub-pixel to convert blue light in the blue backlight into red light, a green quantum dot conversion unit is arranged in a green sub-pixel to convert blue light in the blue backlight into green light, and the backlight source is blue light, so that no quantum dot is arranged in the blue sub-pixel, and the blue light directly penetrates through the blue light.
In the design process of the sub-pixel in the prior art, the red sub-pixel, the green sub-pixel and the blue sub-pixel are equal in length and equal in width, namely the width ratio of the red sub-pixel, the green sub-pixel and the blue sub-pixel is 1:1:1, and the area ratio of the red sub-pixel, the green sub-pixel and the blue sub-pixel is 1:1:1.
As shown in fig. 2, which is a schematic diagram of the area ratio of the red, green and blue sub-pixels, the red, green and blue sub-pixels R, G and B in fig. 2 are equal in length and width, so that the width of the red sub-pixel is Wr, the width of the green sub-pixel is Wg, the width of the blue sub-pixel is Wb, Wr: wg: wb is 1:1:1.
The blue sub-pixel can directly transmit without conversion, so that the transmittance of the blue sub-pixel is close to 100%, and the red sub-pixel and the green sub-pixel need to be converted through quantum dots, so that the transmittances of the red sub-pixel and the green sub-pixel are less than 100%, and the light conversion rates of the red sub-pixel and the green sub-pixel are only about 60% -70%, so that the light transmittances of the red sub-pixel, the green sub-pixel and the green sub-pixel are greatly different.
The white picture finally required by the terminal is generated by mixing red, green and blue sub-pixels according to a certain proportion, and the energy ratio of the red, green and blue sub-pixels is 1:1: 1-1: 1:1.3, as shown in fig. 3 (envelope area of red, green and blue light bands), if the area of the red, green and blue sub-pixels is designed according to a ratio of 1:1:1, the blue light transmitted by the blue sub-pixels is redundant, and the redundant blue light needs to be filtered, which will cause energy waste.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The particle size of the quantum dot material is small and can reach the nanometer level, for example, the particle diameter of the red and green quantum dot materials commonly used by people is about 3-7 nm (nanometer), so the absorption efficiency of the quantum dot is high and can reach more than 90%, and the quantum dot can be allowed to be placed in a display panel to replace a color filter with low transmittance in the panel.
When the backlight source is a blue backlight source and quantum dots are adopted for filtering, because blue light emitted by the blue backlight source does not need to be converted, the transmittance of the blue light is 100%, red light and green light need to be converted by a red sub-pixel and a green sub-pixel, the conversion rate of the blue light emitted by the backlight source into the red light and the green light by the quantum dots is about 60-70%, 50% of the blue light is subjected to backward scattering after being converted by the quantum dots, namely 30-35% of the light is subjected to backward scattering, 50% of the backward scattering light is reflected by a wire grid polarizer and then emitted in a forward direction, the light emitted in the forward direction is 15-17.5% after being reflected by the wire grid polarizer, the light emitted in the forward direction and the light directly converted into the forward direction are added together and are 0.45-0.525 and approximately equal to 0.45-0.53, so that the red sub-pixel, the actual transmittance ratio of red light, green light and blue light in the green sub-pixel and the blue sub-pixel is 0.45-0.53: 0.45-0.53: 1.
in order to make the energy ratio of transmitted red light, green light and blue light close to 1:1:1, reducing the waste of energy, changing the area ratio of the existing red sub-pixel, green sub-pixel and blue sub-pixel to be 1:1:1, and setting the area ratio of the red sub-pixel, green sub-pixel and blue sub-pixel to make the energy ratio of red light, green light and blue light obtained by the blue backlight source transmitting the pixel unit approach to 1:1:1.
in order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments.
