Embodiment Construction

[0039] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0040] Such as figure 1 As shown, generally, after the pixel defining layer 200 for defining the pixel unit 300 is formed on the substrate 100 , the pixel defining layer 200 is further provided with a support post 400 . After the substrate 100 and the packaging cover 500 are packaged, th...

Abstract

The invention relates to a display screen. Each pixel unit of the display screen is provided with a support column; and the length direction of the support column is not parallel to the side edge of any sub-pixel in the pixel unit, so that the support column can be obliquely arranged in the pixel unit relative to each sub-pixel, and the nearest distance between the support column and one sub-pixelis increased. Due to arrangement of the support columns, the nearest distance between each support column and one sub-pixel can be increased, so that the sub-pixel is not prone to being evaporated tothe support column during evaporation, and the situation that after the thicker sub-pixels are evaporated to the support columns, the support columns are damaged due to nonuniform extrusion force applied by a cover plate is prevented.

Description

technical field [0001] The invention relates to display technology, in particular to a display screen and a display device. Background technique [0002] The packaging of the display screen usually uses packaging materials to seal the packaging cover plate and the glass substrate on which the display layer is evaporated, so that water and oxygen molecules from the outside cannot enter the inside of the display screen. [0003] In the conventional technology, after the pixel defining layer and the support pillars disposed on the pixel defining layer are formed on the glass substrate, the light-emitting sub-pixels are usually vapor-deposited in the pits formed by the pixel defining layer by using a mask. The luminescent sub-pixels of different colors have different evaporation thicknesses. [0004] The applicant discovered in the process of realizing the traditional technology that: in the traditional display manufacturing technology, when evaporating the luminous pixels, due...
