Embodiment Construction

[0022] 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.

[0023] It should be noted that when an element is referred to as being “disposed on” or “formed on” another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly c...

Abstract

The invention relates to a display module and a display screen. The display module comprises a plurality of light emitting units and pixel defining layers between adjacent light emitting units. Wherein the pixel defining layer includes a first pixel defining layer and a second pixel defining layer formed on the first pixel defining layer, the first pixel defining layer having a modulus of elasticity smaller than the modulus of elasticity of the second pixel defining layer. By dividing the pixel defining layer into a first pixel defining layer and a second pixel defining layer, and the elasticmodulus of the first pixel limiting layer is different from the elastic modulus of the second pixel limiting layer, which can effectively solve the problem that the stress of the display module is tooconcentrated when the display module is impacted by a foreign object, wherein the pixel limiting layer with small elastic modulus can be used as a flexible buffer layer to avoid stress concentration.

Description

technical field [0001] The invention relates to the display field, in particular to a display module and a display screen. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display panel, also known as organic electroluminescent display panel, is a new type of flat panel display device. High, light and thin, fast response, and easy to achieve color display and large-screen display, easy to achieve flexible display and other advantages, it has broad application prospects. [0003] After the organic light-emitting diode display panel is manufactured, a series of reliability tests of the display panel are usually required, and the impact resistance of the screen is usually tested by a ball drop test. A phenomenon in which local stress surges, which may cause display abnormalities. [0004] Therefore, when the display panel is subject to an instant impact, the stress on it increases sharply, which easily causes display defects such...
