Problems solved by technology

[0003] However, while having good flexibility, due to material and structural limitations, the impact resistance of OLED display devices is weak. When a heavy object hits an OLED display device, black spots, bright spots, Poor display conditions such as color spots have seriously affected the service life and stability of OLED display devices

Embodiment Construction

[0035] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0036] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to a display panel, a display device provided with the display panel and a display panel forming method. The display panel comprises a display base plate and a packaging unit forpackaging the display base plate. The surface of the side, away from the display base plate, of the packaging unit has residual compressive stress used for offsetting at least part of mechanical force. According to the display panel, the existence of residual compressive stress optimizes the mechanical properties of the surface of the side, away from the display base plate, of the packaging unit,and the impact resistance of the packaging unit is improved. When a falling ball hits the display panel provided with the packaging unit in a reliability test, at least part of the tensile stress generated by cracks formed by the falling ball on the packaging unit is offset with the residual compressive stress on the surface of the packaging unit, so that the impact force on the display base plate positioned below the packaging unit is effectively reduced, and the display base plate is prevented from being damaged.

Description

technical field [0001] The present invention relates to the field of display devices, in particular to a display panel, a display device provided with the same, and a method for forming the display panel. Background technique [0002] In recent years, with the development of society and the advancement of science and technology, the technological development of smart terminal equipment and wearable equipment is changing rapidly, and the requirements for flat panel display are gradually increasing, and the demand is becoming more and more diverse. OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display device has lower power consumption compared with liquid crystal display, and at the same time has higher brightness and response speed, and can be bent and has good flexibility, so it is more and more used. It is more widely used in smart terminal products such as mobile phones, tablet computers and even TVs, and has become the mainstream display in the displa...
