Display panel and preparation method thereof, display

Abstract

The invention discloses a display panel and a preparation method thereof, and a display. Therefore, the display panel is prevented against overtemperature of at a local part in order to ensure that the temperature of an overall screen region for the display panel is balanced, preventing the display from working abnormally. The display panel comprises an upper substrate and a lower substrate. The n upper substrate and the lower substrate are aligned to each other through the frame-sealing glue. The frame-sealing glue comprises a basal body of the frame-sealing glue and heat conductive material.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display. Background technique [0002] With the rapid development of the mobile phone industry, customers have higher and higher requirements for the appearance, performance, and display quality of mobile phones, and the corresponding requirements for liquid crystal displays are gradually increasing. The resolution of liquid crystal displays is getting higher and higher, and displays of Full High Definition (FHD), Quarter High Definition (QHD) and even 4K2K are gradually being developed and applied. [0003] The higher the resolution of the liquid crystal display, the higher the requirements on the integrated circuit (IC), and the easier it is to generate heat when the IC is working, causing the local temperature near the liquid crystal display IC to increase significantly. When the temperature is close to or exceeds the c...

AI Technical Summary

Problems solved by technology

When the temperature is close to the clearing point of the liquid crystal or exceeds the clearing point, the dielectric anisotropy of the liquid crystal gradually disappears and does not respond to the action of the electric field. For a normally black fringe field switching (FFS) display, the lighting state is just There will be black defects on the display

Especially now, in order to improve the transmittance of LCDs, negative liquid crystals are usually used. In order to improve the response speed and reduce Vop, negative liquid crystals generally have a low clearing point, so high-resolution negative liquid crystal displays are powered on for a long time or trusted. It is more likely to cause blackening of the display due to excessive local temperature of the display during the performance test and other states

[0004] To sum up, when the existing display is in the state of power-on or reliability test for a long time, the local temperature will be too high, which will make the temperature distribution of the entire screen of the display uneven, which will easily lead to abnormal operation of the display.
