Other features, objects and advantages of the present application will become more apparent upon reading of the following detailed description of non-limiting embodiments thereof, made with reference to the accompanying drawings in which:

FIG. 1 is a schematic diagram of a panel structure capable of being cut to any size in one embodiment;

Fig. 2 is a schematic diagram of a panel structure capable of being cut in any size in another embodiment.

Detailed Description

The present application will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

Referring to fig. 1, the present embodiment provides a panel 1 capable of being cut into any size, wherein the panel is provided with N pixels, the panel 1 includes a first side, a plurality of flip chips 2 are arranged on the first side, and the number of the flip chips 2 is 1.1N-1.2N.

In the embodiment, the arrangement of the chip on film on the panel is increased, so that the sufficiency of the channel use is ensured when the panel is cut in a set size, and the panel can be cut in any size.

The display panel is provided with N pixels, one pixel is usually controlled by one channel, and the position of each chip on film can be used as one channel, so that the chip on film with the same number as or slightly more than the number of the pixels is arranged on each panel to be used as an optional channel to realize the control of the pixels.

Furthermore, the edge of the panel 1 adjacent to the first edge is a second edge, a plurality of chip on films 2 are also arranged on the second edge, and the number of the chip on films 2 on the second edge is 1.1N-1.2N.

The panel shown in fig. 1 is a goa (gate on array) control scheme, the flip chip is disposed on one side of the panel, the display panel shown in fig. 2 is disposed on both sides of the panel, when the first and second sides are both provided with the flip chip, in order to ensure that the panel is cut at any size, the flip chip arranged on the first and second sides needs to be increased, and both sides of the panel are both provided with enough flip chip for adjustment and use.

Furthermore, the number of the flip chip films arranged on the two sides of the center of the panel is the same.

In the embodiment, the preferred number of the flip chip films arranged on the two sides of the center of the panel is the same, which accords with the preparation and arrangement process of the panel in the prior art.

Further, the number of the flip chip on films on the first edge and/or the second edge is 1.2N.

Preferably, the edge of the panel on which the chip on film is arbitrarily arranged is provided with 1.2N chip on film, and the left side of the center line and the right side of the center line are respectively added with 0.1N chip on film by taking the center line of the panel as a boundary, so that the chip on films are distributed on the panel more uniformly, and the cut panel is further ensured to have enough channels for adjustment and use when the panel can be cut on a downward compatible size.

Furthermore, the adjacent flip chips comprise gaps, and the gaps between the adjacent flip chip films are different.

The flip-chip films are distributed on the panel, the number of the flip-chip films is increased to ensure that the cut panel has sufficient channels for use, and the arrangement of the flip-chip films is not completely the same to ensure the effectiveness of panel cutting.

Furthermore, a plurality of size cutting lines 3 are arranged on the panel, and each cutting line 3 is positioned between the adjacent chip on film 2.

As shown in fig. 1 and fig. 2, the dotted line positions in the figures are schematic cutting line positions, and in order to ensure the cutting effectiveness, the positions of the cutting lines that may need to be cut are not provided with the chip on film, that is, each cutting line is located between adjacent chip on films, and when cutting is needed, the positions of the chip on films are not cut.

The panel in this embodiment can be cut downward compatibly, for example, when the size of the panel is 55 inches, the 55 inches panel can be cut to form a panel with a size of less than 55 inches, such as 31.5 inches, 34 inches, 43 inches, etc., and when the flip-chip films are arranged, the cutting lines with the common size can be reserved, that is, the cutting lines with the common size are ensured to be located between the two flip-chip films. In order to ensure the cutting effect and not cause excessive waste, the panel of 31.5-55 inches is preferably set to be cut randomly, and the panel of 55-75 inches is preferably set to be cut randomly, namely, the cutting line of the common panel size below 55 inches is arranged on the panel of 55 inches, and the cutting line of the common panel size between 55-75 inches is arranged on the panel of 75 inches, so as to cut the panel of 55-75 inches, and avoid causing waste.

The present embodiment further provides a display panel, which includes a first liquid crystal panel and a second liquid crystal panel stacked together, where the second liquid crystal panel is the above panel or is formed by cutting the above panel which can be cut in any size.

The second liquid crystal panel in the stacked display panel provided in this embodiment generally needs to be cut, and the panel capable of being cut in any size is used to prepare the second liquid crystal panel, so that resources can be saved, and the purpose of saving development cost can be achieved.

The foregoing description is only exemplary of the preferred embodiments of the application and is illustrative of the principles of the technology employed. It will be appreciated by a person skilled in the art that the scope of the invention as referred to in the present application is not limited to the embodiments with a specific combination of the above-mentioned features, but also covers other embodiments with any combination of the above-mentioned features or their equivalents without departing from the inventive concept. For example, the above features may be replaced with (but not limited to) features having similar functions disclosed in the present application.
