Embodiment approach

[0033] Since the volume is the product of length, width and thickness, the purpose of reducing the volume of the blue sub-pixel at the edge of the display area can be achieved by reducing the width or thickness of the blue sub-pixel.

[0034] The first embodiment, such as figure 1 As shown, the width of the blue sub-pixel 11 in the edge portion A of the display area is smaller than the width of the blue sub-pixel 11 in the central portion B of the display area, and gradually decreases along the direction away from the central portion B of the display area. The width of the blue sub-pixels 11 in the edge portion A of the display area may decrease column by column, or at least once every 2 columns. Usually, the width of the sub-pixel is between 20-30 microns, therefore, the reduction of the width of the blue sub-pixel 11 should not exceed 1 micron each time, so as to avoid the reduction of the blue light passing through the pixel when the reduction is too large Too much, which in...

Abstract

The invention discloses a color film substrate and a display device, relates to the field of display technologies, and solves the problem that the edge part of the existing display device is blue, and the more far away from the central part of the display device, the bluer the part is. The color film substrate provided by the embodiment of the invention includes a display area, wherein the display area is distributed with pixels arranged in arrays, each pixel includes a blue sub-pixel including blue resin material, the proportion of the blue resin material in one pixel at the edge part of the display area is smaller than that of the blue resin material in one pixel at the central part of the display area, and the proportion of the blue resin material is gradually reduced along the direction away from the central part of the display area. The embodiment of the invention also provides a display device including the color film substrate.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a color filter substrate and a display device. Background technique [0002] Quantum dots are nanoparticles that absorb certain wavelengths of light and emit light at other wavelengths. According to the wavelength of emitted light, that is, the color of light, quantum dots can be classified into red quantum dots, green quantum dots, and yellow quantum dots. [0003] Quantum dots have the advantages of high luminous efficiency and high color gamut, and have been used in cutting-edge high color gamut backlight modules. The specific application method is: blue light-emitting diodes are combined with quantum dot films that absorb blue light and emit white light. The quantum dot film material includes quantum dots capable of emitting light of different colors, and the white light emitted by the backlight module is formed by mixing the lights of different colors emitted by va...
