LCD MODULE of the present utility model, the side surface that backboard deviates from liquid crystal panel is provided with groove, when pcb board is installed, in all or part of embedding groove of pcb board, the thickness of the segment thickness of backboard and pcb board stack like this, the integral thickness of LCD MODULE has reduced the thickness of pcb board, thereby the integral thickness of LCD MODULE diminishes, and is more light.

Below by the drawings and specific embodiments, the technical solution of the utility model is described in further detail.

LCD MODULE first embodiment

Fig. 2 is the partial structurtes synoptic diagram of the utility model LCD MODULE first embodiment, as shown in Figure 2, LCD MODULE comprises the liquid crystal panel that is embedded in framework housing 3, module backlight and pcb board 2, and liquid crystal panel comprises color membrane substrates 10 and array base palte 11.Module backlight comprises reflecting plate 1, backlight 7, light guide plate 8, optical film 9, module backlight is fixed in mold framework 23 and the backboard 21, pcb board 2 is provided with electronic component 4, the outside mask of pcb board 2 is provided with overlay 6, overlay 6 can be aluminum plate or plastic foil, can be fixed on backboard 21 and/or the housing 3 by the mode of screw screw or the mode of gummed.The side surface that backboard 21 deviates from liquid crystal panel is provided with groove 22, and pcb board 2 partly or entirely is embedded and is contained in the groove 22, and electronic component 4 can be arranged on the surface that pcb board 2 deviates from backboard 21.Groove 22 can be positioned at the optional position on the side surface that backboard 21 deviates from liquid crystal panel, the shape that the shape of the pcb board 2 that groove 22 is arranged to and is embedded is complementary.

In the installation process of LCD MODULE, all embed pcb board in the groove, like this, the segment thickness of backboard and the stack of the thickness of pcb board, thereby the integral thickness of LCD MODULE is on the basis of available liquid crystal display module thickness, reduced the thickness of pcb board, integral thickness diminishes, and LCD MODULE is also lighter.

LCD MODULE second embodiment

Fig. 3 is the partial structurtes synoptic diagram of the utility model LCD MODULE second embodiment, as shown in Figure 3, different with first embodiment is, the shape that backboard 21 deviates from an end of the shape of the groove 22 that is provided with on the side surface of liquid crystal panel and pcb board 2 is complementary.
