Description

Backlight module and liquid crystal display module

technical field

The invention relates to a backlight module and a liquid crystal display module, and in particular to a backlight module and a liquid crystal display module with buffer grooves.

Background technique

With the advancement of technology, the technology of the display is also constantly developing and its demand is increasing day by day. In the early days, due to the excellent display quality and technical maturity of the cathode ray tube (Cathode Ray Tube, CRT), it monopolized the display market for many years. However, due to the rise of the concept of green environmental protection recently, based on the characteristics of large energy consumption and large radiation generated by cathode ray tubes, and the limited space for flattening their products, cathode ray tubes cannot meet the market demand for light, thin, short , small, beautiful and low power consumption market trends. Therefore, the thin and light flat panel display (Flat Panel Display, FPD) has gradually replaced the traditional heavy cathode picture tube display. Common flat panel displays include plasma display (Plasma Display Panel, PDP), liquid crystal display (Liquid Crystal Display, LCD) and thin film transistor liquid crystal display (Thin Film Transistor Liquid Crystal Display, TFT-LCD).

Taking the liquid crystal display as an example, in the design of the liquid crystal display module, the frame of the liquid crystal display is often fixed by means of screw locking. With the progress of the times, the requirements for the thickness of the display models are getting thinner and thinner. Not only the display panel becomes thinner, but also the thickness of the display frame becomes thinner. Therefore, when the screws are locked to the frame, the screws will easily squeeze the frame and cause deformation of the frame, and the deformed frame will touch and squeeze the display panel above the frame, resulting in damage and rupture of the display panel. In addition, once the screw is skewed, the risk of damage to the display panel in this fixing method is relatively greater.

Detailed ways

In order to make the above and other objects, features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail with reference to the accompanying drawings.

FIG. 1A is a schematic diagram of a liquid crystal display module of the present invention, and FIG. 1B is a cross-sectional view along line I-I in FIG. 1A. Please refer to FIG. 1A and FIG. 1B at the same time. In this embodiment, the liquid crystal display module 100 includes a frame 110, a backlight 120, a liquid crystal display panel 130, an outer frame 140 and a plurality of locking members 150 (FIG. 1A Only one is schematically shown), wherein the frame 110 , the backlight 120 , the outer frame 140 and a plurality of locking components form a backlight module BL. The frame 140 is disposed on the periphery of the frame 110 and the backlight 120 , and is in contact with the frame 110 and the liquid crystal display panel 130 . The frame 110 has a plurality of fastening holes 116 . The outer frame 140 has a plurality of through holes 142 corresponding to these locking holes 116 (only one is schematically shown in FIG. 1A ), and the locking member 150 is locked in the locking holes 116 and the through holes 142, wherein the locking member 150 fixes the outer frame 140 , the backlight 120 and the liquid crystal display panel 130 on the frame 110 .

Incidentally, the frame 110 and the outer frame 140 are made of metal or plastic, for example. In order to conform to modern people’s concept of thinness and lightness of the liquid crystal display module 100 and the components are easy to manufacture, the frame 110 is mostly made of plastic, and the outer frame 140 is mostly made of plastic. Use metal materials with better rigidity such as stainless steel. In addition, the locking member 150 can be a screw, such as a self-tapping screw.

Fig. 2 is a partial perspective view of the frame and outer frame of Fig. 1A. Please refer to FIG. 1B and FIG. 2 at the same time. In this embodiment, the frame 110 has a backlight accommodating space 112 , a liquid crystal panel supporting surface 114 and a plurality of locking holes 116 (only one is schematically shown in FIG. 2 ). The backlight accommodating space 112 is used for accommodating the backlight 120 , and the liquid crystal display panel 114 is used for carrying the liquid crystal display panel 130 , so that the liquid crystal display panel 130 is located above the backlight source 120 . It can be seen clearly from FIG. 2 that each locking hole 116 is correspondingly disposed under each buffer groove 114a.

In addition, please refer to FIG. 3A . FIG. 3A is a partial schematic diagram of the frame shown in FIG. 1A not locked by the locking member. In this embodiment, the locking hole 116 is located below the liquid crystal panel bearing surface 114, and the liquid crystal panel bearing surface 114 has a plurality of buffer grooves 114a (only one is schematically shown in FIG. 3A ), wherein the buffer grooves 114a A bottom surface is, for example, an arcuate surface. Of course, the bottom surface of the buffer groove 114a can also be of other types.

In detail, please refer to FIG. 3B . FIG. 3B is a partial schematic view of the locking member locked on the frame as shown in FIG. 1A . When the locking member 150 is locked in the locking hole 116 and the through hole 142, the frame 110 will be squeezed by the locking member 150 to cause structural deformation, and the deformed frame 110 will usually place the buffer groove 114a The bottom surface is extruded upwards. In this embodiment, the deformed frame 110 has a buffer space due to the buffer groove 114 a, so it is not easy to squeeze the liquid crystal display panel 130 above the frame 110 . In addition, when the locking member 150 is skewed, the buffer groove 114 a can also provide a buffering effect to avoid damage and breakage of the liquid crystal display panel 130 .

To sum up, because the present invention adopts the buffer groove, when the locking member is locked to the locking hole on the frame, a buffer space can be provided for the frame, so that the frame deformed after being squeezed by the locking member will not Thus squeezed to the top of the LCD panel. In addition, if the locking component is skewed, the buffer groove can also provide a buffering effect to avoid damage and rupture of the liquid crystal display panel.
