Abstract

The invention is suitable for the display field of a TV, an integrated computer, a display, and the like and provides a direct type ultrathin liquid crystal display device. The direct type ultrathin liquid crystal display device comprises a front cover and a back cover which are matched to form a cavity body; and the cavity body is internally provided with a display screen, a diffusion film, light sources, a reflective film and a PCB (Printed Circuit Board), wherein the PCB is provided with a plurality of electronic elements, and the PCB and circuit elements thereon are arranged between the light sources. Compared with the traditional direct type liquid crystal display device, the PCB and the circuit elements thereon are arranged in a space between the light sources, the concept is skillful, the thickness of the display device is remarkably reduced, and the ultra-thinness of the direct type liquid crystal display device is realized.

Description

technical field [0001] The invention is applied to display fields such as TVs, computer all-in-one machines, monitors, etc., and in particular relates to a direct-down ultra-thin liquid crystal display device. Background technique [0002] Existing liquid crystal display devices are generally divided into two types: side-light type and direct-light type. For small and medium sizes, edge-lit display devices have the advantages of lightness, thinness, and low power consumption; however, with the development of technology, the demand for large-size display devices is increasing, and large-size edge-lit display devices accommodate the number of light sources. Limited, low light utilization efficiency, unable to meet the brightness requirements of large-size liquid crystal display devices. The large-size direct-type display device can accommodate more light sources and has high light utilization efficiency, so it is favored by people. However, the existing large-size direct-type...
