Abstract
The utility model discloses a liquid crystal display module and a display device. Chips are effectively protected, so that the quality reliability of the display device is improved. The liquid crystal display module comprises a rubber frame, a front frame and a plurality of chip on films, wherein the chip on films are positioned between the side wall of the rubber frame and the side wall of the front frame; the chips are encapsulated in the chip on films; the liquid crystal display module further comprises protective structural members corresponding to the chip on films positioned between the side wall of the rubber frame and the side wall of the front frame; the protective structural members are provided with concave parts for accommodating the chip on films. When the front frame is deformed due to external extrusion, the protective structural members can be supported between the side wall of the front frame and the side wall of the rubber frame, so that the chip on films are prevented from being extruded, and the chips are protected effectively; through the arrangement of the protective structural members, the overall structure strength of the liquid crystal display module can be increased.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal module and a display device. Background technique [0002] Among flat panel display devices, Thin Film Transistor Liquid Crystal Display (TFT-LCD for short) has the characteristics of small size, low power consumption, relatively low manufacturing cost and no radiation, and occupies a dominant position in the current flat panel display market. leading position. [0003] In TFT-LCD, the chip is packaged in the Chip on Film (COF) between the side wall of the plastic frame and the side wall of the front frame. The chip is an important part of transmitting and processing signals in the TFT-LCD. Even slight damage can cause abnormal display of the LCD module. In the prior art, a more conventional design is to reserve a space for placing the chip on film between the side wall of the plastic frame and the side wall of the front frame, and the front frame can protect ...
