Description

201011395 Z1TW 27358twf-Chimei.doc/e IX. Description of the Invention: [Technical Field] The present invention relates to a liquid crystal display having a good liquid crystal test yield. [Prior Art] ❹ With the rapid development of technology and people's demand for life comfort, the size of the liquid crystal display (4) module is also rapidly increasing, and the manufacturing and assembly tolerances of the liquid machine components are also increasing. FIG. 1A is a schematic diagram of a conventional liquid crystal display. Referring to the drawings, in the crystal display 100, the control circuit board 110 and the liquid crystal display panel 120 are connected by a flexible joint member 13A. Generally, the circuit board 11G can be completely stipulated on the frame 10 (10) of the liquid crystal display _ 丨 (8) by a plurality of methods, for example, by using a snail, and the control circuit board 110 is controlled. Unable to move relative to frame 14 相对. When the liquid crystal display 1 is subjected to mechanical tests such as vibration, falling, etc., it will be;

The display, and particularly with respect to a remaining assembly tolerance, causes the liquid crystal display panel 120 to produce a large displacement instantaneously with respect to the control circuit board 110. The vertical view is a tearing of the tape of the flexible joint of the liquid crystal display. Please refer to FIG. 1 and FIG. 8 at the same time, because the control circuit board 11 () is completely fixed on the frame 140 and cannot move relative to the frame 14 , which may cause connection between the liquid crystal display panel 120 and the control circuit board 110 . The tearing of the strip 132 of the flexible joint member 0 causes the liquid crystal display 1 to fail to be normally driven. Moreover, the wafer 134 disposed on the strip 132 of the flexible joint member 130 may also be affected by the impact force, or may be instantaneously tightened by the material of 201011395 ZITW 27358twf-Chimei.doc/e, 132. The strip 132 is peeled off, which in turn damages the liquid crystal display 100 and affects the yield of the liquid crystal display 10 . Fig. 2A is a schematic view showing a control circuit of a liquid crystal display; & fixed on a frame. Referring to FIG. 2A, a conventional method of fixing the control circuit board 11A to the frame 140 is to lock the control circuit board 110 to the metal frame 140 by means of screws 15. With the screw 150, the need for fixing and grounding the control circuit board 110 can be completed at one time. However, as the liquid crystal display device 100 enters a large-sized design such as a liquid crystal television, since the control circuit board 110 is completely fixed to the frame 140, the gap between the machine members in the liquid crystal television is much larger than that of other liquid crystal products. Therefore, after the test such as shaking or dropping, it is easy to cause the flexible joint member 13 to have damage as shown in FIG. 1A and FIG. = Figure 2B is a schematic diagram of the control circuit board being locked to the frame to control the warpage of the circuit board. Please refer to FIG. 2B, also because the length of the control circuit board 11〇 is also greatly increased. Therefore, by means of the screw 15 〇 locking, it is easy for the control circuit board 110 itself to be warped and deformed due to stress. As shown in FIG. 2B, the uncertainty in the quality of the edge crystal display is increased. Fig. 3 is a schematic view showing a control circuit board of a conventional liquid crystal display mounted on a frame. Referring to Figure 3, another conventional method is to attach the control circuit board 110 to the frame 14 by means of a double-sided tape 160. However, considering the case where the control circuit board 110 needs to be reworked due to the wrong position of the attachment, when the adhesiveness of the double-sided tape 160 is too strong, it is easy to apply force during the process of removing the control circuit board 110 from the frame 140. Causes the belt 6 201011395 Z1TW 27358twf-Chi Mei.doc/e tear. Further, when the adhesiveness of the double-sided tape 160 is too weak, the control circuit board m is fixed to the frame (10). Correction, double-sided tape · When the environmental conditions such as temperature and fishing degree change, the viscosity will change accordingly. The silkiness of the wire can be smothered, and the circuit board can be adhered to the frame 14G or adhered. Too strong is so that the control circuit board H0 is difficult to be separated by the frame 140 during rework. Therefore, the extreme double-sided tape 160 is used. ^ ❹ Figure 4 = No. _, the control circuit board of the liquid crystal display is fixed on the frame. As shown in FIG. 4, a metal dome 170 is soldered on the control board (4), and then a front frame (not shown) or a back frame (not shown) is used according to the position of the control circuit board 11〇. ) to press the metal = m' to control the circuit board 11G. Although this method allows the control m to be fixed on the frame 140, and the control circuit board can move the panel l2G for 3 days, the method must place the control circuit board 110 on the liquid crystal display panel 12. The same plane is used, so that the liquid metering display H _ the outer shape of the control circuit board 11 that is in the same plane as the liquid crystal display panel 120. In addition, in order to be pressed by the front frame or the back frame, the metal dome needs to be formed so that the height of the front frame needs to be increased to accommodate the metal dome (7), which is inconsistent with the design concept of thinning the liquid crystal display HUG.

In addition, by the configuration of the buffer block 2600, the movement of the control circuit board 12 in the Y direction can be appropriately limited, and the buffer block 2_=compressible characteristic can also make the control circuit board 12 (8) have a certain degree in the x direction. The displacement thus prevents the strip 1310 of the flexible joint 1300 from being too tight and broken, thereby maintaining the integrity of the wafer 132, thereby improving the test yield of the liquid crystal display 2000. Moreover, by the configuration of the buffer block 2600, the impact force can be buffered to prevent the control circuit board 1200 from colliding with the frame 2500 to be damaged or broken. 8A to 8D are possible configuration positions of the buffer block. As shown in FIGS. 8A-8D, the punch 2600 can be disposed around the second opening 251 of the frame 2500.
