Display module and installation method of display module

Abstract

The application discloses a display module and a method for installing the display module. The display module includes a display panel, a frame and foam, the display panel is arranged in the frame, and the frame includes a vertical part and a horizontal part perpendicular to each other. , the display panel is arranged above the horizontal part and lower than the top of the vertical part, the display panel is arranged parallel to the horizontal part, a first gap is provided between the display panel and the horizontal part, and a second gap is provided between the display panel and the vertical part Two gaps, the foam includes first foam and second foam, the first foam is arranged in the first gap, the second foam is arranged in the second gap, the first foam and the second foam cover the first The gap and the second gap cover the gap between the display panel and the frame to improve the effect of light leakage between the display panel and the frame, and also save production costs. The side of the second foam close to the display panel is the guide surface , the guide surface is convenient for installing the display panel, and the production speed of the display module is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display module and a method for installing the display module. Background technique [0002] Liquid crystal display modules have many years of development experience, and the technology is relatively mature. However, as the market demand for narrow bezels, or even no bezels, is becoming increasingly strong, various screen manufacturers are also actively responding, striving to produce more competitive products, but In the process of technology development, the most difficult problem is the light leakage problem caused by the narrow frame. The light is transmitted through the gap (Gap) at the edge of the LCD panel (OC, Open-cell) and the backlight module (BLU, Back light unit) , It is visible to the human eye outside the active area of ​​the screen, resulting in poor visual taste. [0003] The industry has proposed a variety of improvement solutions and conducted exp...

Problems solved by technology

[0002] Liquid crystal display modules have many years of development experience, and the technology is relatively mature. However, as the market demand for narrow bezels, or even no bezels, is becoming increasingly strong, various screen manufacturers are also actively responding, striving to produce more competitive products, but In the process of technology development, the most difficult problem is the light leakage problem caused by the narrow frame. The light is transmitted through the gap (Gap) at the edge of the LCD panel (OC, Open-cell) and the backlight module (BLU, Back light unit) , which is visible to the human eye outside the active area of ​​the screen, resulting in poor visual taste

[0003] The industry has proposed a variety of improvement solutions and conducted experimental verification, but the results are not satisfactory. At present, light leakage is still an important item in quality inspection and a key factor affecting yield. Traditional narrow bezel and borderless product designs do not The front frame (UP-Bezel) is used for shading, and the gap between the LCD panel and the frame is 0.4mm, and the light leakage phenomenon is obvious. The existing technology mainly relies on adjusting the offset of the LCD panel to improve, but the effect is not obvious, and it is still possible There will be light leakage problems
