Display module and installation method of display module

Abstract

The invention discloses a display module and an installation method of the display module, the display module comprises a display panel, a frame piece and foam, the display panel is arranged in the frame piece, the frame piece comprises a vertical part and a horizontal part which are perpendicular to each other, the display panel is arranged above the horizontal part and is lower than the top of the vertical part, the display panel and the horizontal part are arranged in parallel, a first gap is formed between the display panel and the horizontal part, a second gap is formed between the display panel and the vertical part, the foam comprises first foam body and second foam body, the first foam body is arranged in the first gap, the second foam body is arranged in the second gap, and the first foam body and the second foam body shield the first gap and the second gap; the gap between the display panel and the frame piece is shielded, the effect of improving light leakage between the display panel and the frame is achieved, meanwhile, the production cost is saved, the side, close to the display panel, of the second foam bodyis the guide face, the display panel is convenient to install through the guide face, and the production speed of the display module is increased.

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.

[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
