Spacer, preparation method of spacer, display device and preparation method of display device

Abstract

The invention relates to a spacer and a preparation method thereof as well as a display device and a preparation method thereof. The spacer comprises a spacer body and a groove, the spacer body comprises a first end and a second end, and the first end is opposite to the second end; the spacer main body is made of an elastic material; the groove is located at the first end of the spacer body, and the first end forms a suction cup when bearing pressure from the second end. According to the embodiment of the invention, the spacer main body is made of the elastic material, the first end of the spacer main body is provided with the groove, and the first end of the spacer main body forms the suction cup when being subjected to the pressure from the second end of the spacer main body, so that the first end of the spacer main body forms the suction cup when the spacer is stressed to deform; the suction force of the sucker can prevent the spacer from sliding.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a spacer and a preparation method thereof, a display device and a preparation method thereof. Background technique [0002] In related technologies, with the investment of high-generation lines and the arrival of the TFT-LCD (thin film transistor-liquid crystal display) flat panel era, the output of large-size TFT-LCDs is increasing, and the spherical spacer spreading process is no longer used by high-tech For generation lines, the original spherical spacers have been replaced by columnar spacers. Moreover, columnar spacers have been widely used in large-sized liquid crystal displays. The working principle of the columnar spacer is: in the process of box alignment between the density distribution of the non-display area on the color filter substrate and the columnar spacer at a specific height and the non-display area of ​​the array substrate, and during the use of the liquid c...

AI Technical Summary

Problems solved by technology

However, during the production process and the use of the liquid crystal display, the spacer will be squeezed and deformed in a certain area where the spacer is in contact with the array substrate, and the spacer will slide to the pixel area of ​​the array substrate, scratching the display area on the side of the array substrate. Alignment film, resulting in blue spots

Moreover, the recovery force of the liquid crystal display is insufficient after the force disappears, the color filter substrate and the array substrate cannot return to their original positions, and the black matrix cannot completely cover the backlight, causing light to leak from the display area, resulting in light leakage

In addition, when the liquid crystal display is placed vertically for a long time, the liquid crystal will be piled up towards the bottom and corners of the display due to gravity (especially in the case of high temperature), which will make the box thicker and cause abnormal colors
