Description

Technical Field

[0001] This utility model relates to the field of display module technology, and in particular to a narrow-bezel display panel that is easy to quickly test. Background Technology

[0002] In the display panel industry, a series of reliability verifications are required after panel production. One crucial aspect is the rapid electrical testing of the panel. By illuminating the glass using an electrical testing fixture, panels with display abnormalities are initially screened out. Rapid panel testing is a vital step. Patent application CN202421235746.6 discloses an integrated touch display panel, comprising: a bonding area, including a rapid testing Pad, on which a rapid testing FPC is bonded. The rapid testing FPC has rapid testing pins. This display panel, by bonding the rapid testing FPC to the rapid testing Pad, and the rapid testing FPC having rapid testing pins, also includes a main FPC bonding bit in the bonding area. The main FPC is used to connect to a client. The rapid testing FPC and the main FPC are an integrated structure. The bonding area also includes an IC bonding bit for connecting an IC. In this display panel, the fast test FPC extends beyond the display screen. When testing the display screen, only the fast test pins need to be connected; there's no need to scrape open the IC protective layer, thus avoiding damage to the display screen. Conventional panel structures design the fast test pad inside the panel. However, when encountering small-sized panels or narrow-bezel panels, the layout space for the fast test pad is compressed. This results in the fast test pad being too small, and some fast test signal lines not being able to be properly extended, ultimately affecting the normal display of the panel. Therefore, this utility model discloses a narrow-bezel display panel that facilitates fast test and solves the above problems. Utility Model Content

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0026] As described in the background section, the conventional panel structure places the quick detection pad inside the panel. However, when dealing with small-sized panels and narrow-bezel panels, the layout space for the quick detection pad is compressed, resulting in the quick detection pad being too small and some quick detection signal lines not being able to be pulled out properly, ultimately affecting the normal display of the panel.

[0027] To address this technical problem, this invention provides a narrow-bezel display panel that facilitates rapid testing and is applicable to the field of display modules.

[0028] For details, please refer to Figure 1-5 The narrow bezel display panel that facilitates rapid testing specifically includes a display panel 1. The display panel 1 has a visible area 2 and a side GIP area 3. The GIP area 3 is provided with a driving circuit. The display panel 1 has an outwardly extending Dummy area 4 on its side. The Dummy area 4 is provided with a rapid test Pad 5. The rapid test Pad 5 is electrically connected to the driving circuit of the GIP area 3 through a signal line.

[0029] The present invention provides a narrow-bezel display panel 1 that facilitates rapid testing. By adding a dummy area 4 to the display panel 1, the setting area of ​​the rapid testing Pad 5 is expanded, ensuring the layout space of the rapid testing Pad 5 and facilitating the layout design of the rapid testing Pad 5. After the rapid electrical test is completed, the dummy area 4 is removed, thereby achieving a small-size, narrow-bezel panel design without affecting the normal rapid testing of the panel.

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0031] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] Example 1

[0034] Please refer to Figure 1-2 A narrow-bezel display panel for easy rapid testing is provided, comprising a display panel 1, which is an LCD, specifically an LTPS panel. The display panel 1 has a visible area 2 and a side-mounted GIP area 3. The GIP area 3 is located in the non-visible area of ​​the display panel 1 and surrounds the visible area 2. The GIP area 3 is equipped with a driving circuit. The display panel 1 has an extended dummy area 4 on its side. The dummy area 4 is equipped with a rapid test pad 5. The rapid test pad 5 is electrically connected to the driving circuit of the GIP area 3 through a signal line. By extending the dummy area 4, the edge area of ​​the display panel 1 is increased, thereby increasing the layout space of the rapid test pad 5 and reducing the design difficulty of the rapid test pad 5. It is suitable for small-sized and narrow-bezel display panels 1.

[0035] Furthermore, the GIP area 3 is distributed on both sides of the visible area 2, and the Dummy area 4 is set close to the side of the GIP area 3 away from the visible area 2. There are two quick test Pads 5, which are distributed in two Dummy areas 4 outside the GIP area 3. That is, each Dummy area 4 is equipped with a quick test Pad 5 for the driving circuit on the corresponding side of the GIP area 3. During the quick test, the quick test rack provides a power signal to the quick test Pads 5 on both sides, thereby lighting up the display panel 1. The display panel 1 with display abnormalities can be identified by human eyes.

[0036] Furthermore, the display panel 1 has a binding area 6, which is equipped with a driver IC 7 and an FPC binding bit 8. The FPC binding bit 8 is used to bind the main screen FPC.

[0037] Furthermore, the display panel 1 includes an array substrate 9 and a color filter substrate 10 stacked together, and a liquid crystal layer disposed between the array substrate 9 and the color filter substrate 10. The width of the array substrate 9 is greater than the width of the color filter substrate 10. Both sides of the array substrate 9 extend beyond the edge of the color filter substrate 10 in the width direction, forming a dummy region 4. The length of the array substrate 9 is greater than the length of the color filter substrate 10. One end of the array substrate 9 extends beyond the edge of the color filter substrate 10 in the length direction, forming a bonding region 6. During fabrication, the array substrate 9 is extended in the width direction to widen the original substrate of the array substrate 9. The widened portion is the dummy region 4. The portion of the array substrate 9 extending in the length direction forms a single-layer bonding region 6, which is used to arrange the driver IC 7 and set the FPC bonding position 8.

[0038] Furthermore, the bottom substrate of the array substrate 9 is a rigid substrate or a flexible substrate, and the bottom substrate of the color filter substrate 10 is matched with the bottom substrate of the array substrate 9. The rigid substrate is a glass substrate, specifically soda-lime glass or alkali-free glass, and the flexible substrate is made of polyimide material for flexible OLEDs.

[0039] Example 2

[0040] The narrow bezel display panel provided in Embodiment 1, which facilitates rapid testing, is further optimized, specifically, as follows: Figure 3 As shown, the dummy area 4 is located on both sides of the display panel 1 near the bonding area 6. Only the part of the display panel 1 near the bonding area 6 is extended outward to form the dummy area 4, thereby reducing the use of materials. Each quick test Pad 5 has multiple test contacts. In the layout design of the quick test Pad 5, the multiple test contacts are distributed in the dummy area 4 and the bonding area 6 respectively. This not only makes use of the original bonding area 6 position, but also reduces the layout space required for the dummy area 4, thereby further reducing the use of materials and reducing production costs.

[0041] Example 3

[0042] The narrow bezel display panel provided in Embodiment 2, which facilitates rapid testing, is further optimized, specifically, as follows: Figure 4-5 As shown, in this example, the bottom substrate of the array substrate 9 is a flexible substrate board made of polyimide. An easy-tear line 11 is provided at the junction of the array substrate 9 and the dummy area 4. The easy-tear line 11 has a linear dotted hole structure, and U-shaped, V-shaped or semi-circular easy-tear openings 12 are provided at both ends of the easy-tear line 11. After the panel is quickly inspected, it is convenient to tear off the array substrate 9 from the dummy area 4, thereby improving processing efficiency, reducing the investment in cutting equipment, and reducing costs.

[0043] It is worth noting that in this utility model, Panel refers to the display panel 1, Dummy area 4 is a blank panel, that is, a blank board without circuit structure. Quick test Pad 5 is a key test point used for rapid electrical performance testing. Quick test Pad 5 is a set of metal contacts (Test Pad) exposed on the edge of the array substrate 9. It is directly contacted by probes or test equipment and used to quickly test the electrical performance of the panel circuit (such as conductivity, impedance, signal integrity, etc.).

[0044] The working principle of the narrow bezel display panel for rapid testing provided by this utility model is as follows: During the fabrication of the display panel 1, the array substrate 9 is widened in the width direction. After the color filter substrate 10 is bonded and assembled with the array substrate 9, the widened part extends out on both sides of the color filter substrate 10 to form a dummy area 4. The dummy area 4 is used to arrange the rapid testing Pad 5, thereby expanding the setting area of ​​the rapid testing Pad 5, ensuring the layout space of the rapid testing Pad 5, and facilitating the layout design of the rapid testing Pad 5. After the rapid electrical test is completed, the dummy area 4 is cut off, thereby achieving a small-size, narrow-bezel panel design without affecting the normal rapid testing of the panel.
