Display module

Abstract

The invention discloses a display module which comprises a display panel and a frame part. The frame part is arranged around the display panel, and comprises a horizontal part and a vertical part; the horizontal part is perpendicular to the vertical part, a gap is formed between the vertical part of the frame part and the side face of the display panel, and a bearing surface used for bearing the display panel is formed at the horizontal part of the frame part. The display module further comprises foam, the foam is arranged in the gap, and the thickness of the foam is larger than or equal to the width of the gap. The foam with the thickness larger than that of the gap is filled into the gap, and the gap can be completely filled, and therefore light rays emitted to the gap from the side face of the display panel are shielded, the emission of the light rays from the side face is reduced, and light leakage is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a 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 caused by the narrow frame. The light passes through the gap (Gap) between the display panel (OC, Open-cell) and the edge of the backlight module (BLU, Back light unit). It is visible 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...

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 caused by the narrow frame. The light passes through the gap (Gap) between the display panel (OC, Open-cell) and the edge of the backlight module (BLU, Back light unit). come out and be visible to the human eye outside the screen's luminous surface (ActiveArea), resulting in poor visual taste

[0003] The industry has proposed a variety of improvement solutions and conducted experimental verifications, 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 shading, and the gap (Gap) between the display panel (OC, Open-cell) and the frame is 0.4mm, and the light leakage phenomenon is obvious. The existing technology mainly relies on adjusting the display panel (OC, Open-cell) -cell) partial paste method to improve, the effect is not obvious, and the cost is high
