Embodiment Construction

[0038] As mentioned in the background art, users have higher and higher requirements on display clarity and service life of display panels. figure 1 Shown is a schematic diagram of a Diamond pixel structure provided in the prior art. Such as figure 1 As shown, there are light-emitting areas (11, 21, 31 in the figure) and non-light-emitting areas (12, 22, 32 in the figure) in each sub-pixel unit, wherein the non-light-emitting areas (12, 22, 32 in the figure) are composed of pixels The design margin reserved in the manufacturing process. Due to the existence of design margin, fixed screen size, pixel aperture ratio and PPI are negatively correlated, the larger the PPI, the smaller the aperture ratio, and the smaller the PPI, the larger the aperture ratio. The larger the PPI, the higher the clarity, and the larger the aperture ratio, the higher the light extraction efficiency. Fixed screen size, the same PPI requirement, the same luminous flux requirement, the smaller the ape...

Abstract

The invention provides a pixel structure, which comprises a plurality of pixel units arranged in an array, and is characterized in that each pixel unit comprises a first sub-pixel, a second sub-pixeland a third sub-pixel which are arranged in the diagonal direction of the array; the two adjacent pixel units in the same row are symmetrically arranged, the two adjacent pixel units in the same column are symmetrically arranged, and each first sub-pixel and each third sub-pixel are shared by the four pixel units; and the shape of the second sub-pixel is matched with the shape of a gap area between the first sub-pixel and the third sub-pixel which are adjacent to each other in the diagonal direction. Because the shape of the second sub-pixel is matched with the shape of the gap area between the first sub-pixel and the third sub-pixel which are adjacent in the diagonal direction, compared with the same PPI pixel arrangement mode in the prior art, the aperture opening ratio of the same PPI is improved, the higher the light emitting efficiency is improved, the higher the unit point current is reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a pixel structure and a preparation method thereof. Background technique [0002] With the development of display technology, users have higher and higher requirements on display clarity and service life of display panels. Fixed screen size, the same PPI value, the same luminous flux requirements, the smaller the aperture ratio, the lower the light extraction efficiency, the larger the current per point, the shorter the life of organic materials, therefore, there is an urgent need for an improved pixel arrangement structure that can meet High PPI requirements can increase the aperture ratio and prolong the service life under the premise of meeting the same PPI. Contents of the invention [0003] In view of this, the embodiment of the present invention provides a pixel arrangement structure, compared with the pixel arrangement structure in the prior art, the aperture ratio is ...
