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” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected t...

Abstract

The invention relates to a display module and a display screen. The display module includes: an array substrate and a planarization layer formed on the array substrate. Wherein, the planarization layer includes a first planarization layer formed on the array substrate and a second planarization layer formed on the first planarization layer, and the elastic modulus of the first planarization layer is less than or greater than elastic modulus of the second planarization layer. By dividing the planarization layer into the first planarization layer and the second planarization layer, and the elastic modulus of the first planarization layer is different from the elastic modulus of the second planarization layer, it can effectively solve the problems caused by the display module. For the problem of excessive stress concentration when impacted by foreign objects, the flattened layer with a 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...
