Background technique

Among the current displays, liquid crystal displays have the advantages of high image quality, small size, light weight, low voltage drive, and low power consumption, so they have been widely used in portable TVs, mobile phones, video recorders, notebook computers, desktops, etc. In consumer electronics or computer products such as monitors and projection TVs, it has become the mainstream of monitors.

The liquid crystal display mainly includes components such as a liquid crystal display panel, a backlight module, and a frame. In the process of transporting the liquid crystal display panel, in order to avoid damage to the liquid crystal display panel due to collision during transport, packing boxes are often used to load it. As shown in Figure 1, the display board 1 is an example of a common liquid crystal display panel. The liquid crystal display panel (semi-finished board) includes a main display board 2, a flexible printed circuit board 3, a rigid printed circuit board 4, and some flexible printed circuit boards. It is only connected to the main display board 2, and part of the flexible printed circuit board is connected to the main display board 2 and the rigid printed circuit board 4 at the same time (or the rigid printed circuit board 4 is connected to the main display board through the flexible printed circuit board 3 2 connections). Usually, one side of the rigid printed circuit board 4 has no components, so this surface is a smooth surface; while the other side has a rough structure because multiple components are installed, and the heights of each component are different. The main display panel 2 includes a color filter substrate, an array substrate, and a liquid crystal layer disposed between the color filter substrate and the array substrate. When the liquid crystal display panel is placed on a horizontal plane, generally the color filter substrate of the main display panel 2 faces upward, the array substrate of the main display panel 2 faces downward, and the rigid printed circuit board 4 connected to the main display panel 2 through the flexible printed circuit board 3 Generally, the smooth side faces down, and the side connected with components faces up. And when using the packaging box to load the liquid crystal display panel, usually the one side of the array substrate of the main display panel 2 is facing the bottom of the box in the packaging box, and the one side of the color filter substrate of the main display panel 2 is facing the side of the box. opening. A packing box is usually loaded with multiple liquid crystal display panels.

In the same liquid crystal display panel, the rigid printed circuit board 4 is thicker than the main display board 2 . When a plurality of identical liquid crystal display panels are loaded in the box, first place a liquid crystal display panel in the box, then place a spacer on the liquid crystal display panel, and then superimpose another liquid crystal display panel on the spacer, Until all the liquid crystal display panels are placed in the box. Since the rigid printed circuit board 4 is connected to the main display panel 2 through the flexible printed circuit board 3, after a plurality of liquid crystal display panels are placed in the box, a plurality of rigid printed circuit boards 4 are also stacked. The plane of the rigid printed circuit board 4 closest to the opening of the box in the body is much higher than the plane of the main display board 2 connected to it through the flexible printed circuit board 3 . If whether packing case is filled with liquid crystal display panel is based on whether main display panel 2 arrives at the opening of the casing of packing case as judgment standard, the height of rigid printed circuit board 4 that is in the highest position in the casing will be higher than the height of casing so opening, thereby causing the packaging box to be unable to be sealed through the upper cover 15; and if the package transfer box is filled with liquid crystal display panels, whether the rigid printed circuit board 4 reaches the opening of the box body of the packaging box is used as a criterion for judging, then in the box The height of the main display panel 2 will be lower than the opening of the box body 6, which will cause a waste of the loading volume of the box body of the packaging box, thereby greatly reducing the number of liquid crystal display panels that can be loaded in the box body. Moreover, during the transportation of the packing box, since the main display board 2 and the rigid printed circuit board 4 of the same liquid crystal display panel are not on the same plane, vibrations are likely to be caused between the main display board 2 and the rigid printed circuit board 4, thereby causing the same liquid crystal The flexible printed circuit board 3 between the main display board 2 and the rigid printed circuit board 4 of the display panel is prone to breakage. At present, not only the above-mentioned liquid crystal display panels, but also other types of display panels, such as plasma display panels, organic light-emitting diode display panels, or drivable main display panels that have not yet been formed into a box but have been connected to a driving circuit board, are packaged Also there is above-mentioned problem in the process or in the storage and transport moving process after packing. Of course, the figures shown in Fig. 1 are not limited to represent liquid crystal display panels, but may also represent other types of display panels, such as plasma display panels, organic light-emitting diode display panels, or display panels that have not yet been formed into a box but have been connected to a driver The circuit board can drive the main display board.
