Problems solved by technology
[0003] Due to the limitation of material development, the light-emitting device of AMOLED display device has a low lifespan, especially the lifespan of blue light, and the deterioration is accelerated in an environment with high operating temperature, and the lifespan is shorter
However, the difference in device degradation in AMOLED displays will cause aging problems in some areas of the display screen first, affecting the display effect of the entire screen, and even causing the screen body to be scrapped in advance
[0004] The luminescent material of AMOLED is mainly affected by water vapor and oxygen, so the conventional solution is to continuously improve the packaging technology to avoid deterioration differences, but the current packaging technology is difficult to improve
In addition, in a high-temperature environment, the physical reaction of expansion at the interface of the package will accelerate the entry of water and oxygen, accelerate aging, and lead to a shorter life of the light-emitting device

Embodiment Construction
[0022] 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.
[0023] 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. In contrast, when an element is referred to as being "directly on" another element, there are no interveni...

The invention relates to a cooling device of a displayer and the displayer provided with the cooling device. The cooling device of the displayer comprises a driving chip and a plurality of cooling units, and the driving chip is used for receiving temperature signals of the external displayer and carrying out data processing. Each cooling unit comprises a switch module and a cooling assembly. The driving chip drives each cooling assembly to work through the corresponding switch module. According to the cooling device and the displayer, after receiving the temperature signals fed back by the outside, the driving chip processes and judges an area needing cooling and controls the cooling units to selectively work in a progressive scanning mode; when making contact with a screen body, the cooling units can dissipate heat of the screen body, and therefore the screen body can be cooled selectively.
Description
technical field [0001] The invention relates to the technical field of flat panel display, in particular to a display cooling device and a display. Background technique [0002] Compared with traditional liquid crystal panels, AMOLED (Active Matrix / Organic Light Emitting Diode, active matrix organic light emitting diode panel) has the characteristics of faster response speed, higher contrast ratio, and wider viewing angle. Therefore, it is widely used in many fields, such as flat panel display, display backlight and other fields. [0003] The light-emitting device of the AMOLED display device is limited by material development, and the life of the light-emitting device, especially the blue light life, is relatively low, and the deterioration is accelerated in an environment with high operating temperature, and the life is shorter. However, the difference in device degradation in AMOLED displays will cause aging problems in some areas of the display screen first, affecting t...
