Description

Technical Field

[0001] The present invention belongs to the technical field of display devices, and in particular relates to a connector and a display screen. Background Art

[0002] Transparent display screens do not block sunlight and have a see-through effect. They are often used in glass curtain wall buildings, airports, hotels, stages, store windows and other occasions. For example, office buildings, exhibition centers, airports, hotels, stages and other large buildings in commercial complexes and indoor environments of commercial spaces are ideal for retaining the visual depth of the space. At the same time, they can also allow cool multimedia effects to show more visual layers and impact large shopping malls and chain stores. Transparent display screens perfectly combine modern artistic beauty with metal shapes, showing the advantages of high transparency, that is, after the installation of transparent display screens, they do not affect the original architectural style and lighting. They have texture in product shape and are also new products of modern architectural advertising. They can be widely used in glass curtain walls, large shopping malls, glass partitions and so on.

[0003] The display screen needs to be connected to an external control circuit when in use. The display screen is usually made of glass. In order to avoid damage to the display screen or affect the display effect caused by rigid connection, an FPC connector is usually used to achieve a flexible connection between the display screen and the external control circuit. However, the connector in the prior art has the problem of reducing the effective display area or display effect of the display screen when in use; specifically, there are power supply lines and signal lines in the display screen, and in order to avoid interference caused by the intersection of the signal circuit and the power circuit, and also for the simplicity of wiring (only one-side wiring can be performed on the display screen), the power terminals and signal terminals on the display screen need to be divided into two rows. Further, when the connector is connected to the display screen, the power pad on the FPC is located above the light-emitting unit (lamp bead or pixel unit) closest to the display screen body 6, while the signal terminal pad is close to the edge of the display screen glass circuit and below the light-emitting unit (lamp bead or pixel unit). At the same time, since the power terminals and signal terminals on the display screen are divided into two rows, the FPC circuit board will block the light-emitting unit (display pixel point) between the power terminals and the signal terminals on the display screen to form a light-emitting blind area, thereby reducing the effective display area of ​​the display screen or affecting the display effect of the display screen.

[0028] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments cited are not intended to limit the present invention.

[0029] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element and integrated therewith, or there may be an intermediate element at the same time. The terms "installed", "one end", "the other end" and similar expressions used in the present invention are for illustrative purposes only.

[0030] like Figure 1-2As shown, this embodiment provides an electrical connector, which includes a substrate 1 and a first connection area 2 and a second connection area 3 respectively arranged on the substrate 1; wherein, a plurality of pads and a plurality of through holes 23 are arranged in the first connection area 2, and the pads are arranged around the through holes 23; a plurality of conductive contacts are arranged in the second connection area 3, and the plurality of pads and the plurality of conductive contacts are electrically connected through a conductive line 4 arranged on the substrate 1. Further, the plurality of through holes 23 are arranged in rows, and at the same time, the plurality of pads are also arranged in rows; the pads in the first connection area 2 include a plurality of signal terminal pads 21 and a plurality of power terminal pads 22, and the plurality of signal terminal pads 21 and the plurality of power terminal pads 22 are arranged in rows, and the rows are arranged at intervals. Among them, the through hole 23 is located between the row lines of the signal terminal pad 21 and the power terminal pad 22. Further, relative to the arrangement row lines of the signal terminal pad 21 and / or the power terminal pad 22, at least part of the through hole 23 is staggered with the signal terminal pad 21, or at least part of the through hole 23 is staggered with the power terminal pad 22; or in the longitudinal direction, the through hole 23 is located between the column lines. Specifically, there will inevitably be power supply lines and signal lines in the display screen. In order to avoid the interference of the signal lines caused by the intersection of the signal lines and the power lines of the display screen, and also for the simplicity of wiring, the power terminals and signal terminals on the display screen need to be divided into two rows. Further, when the connector is connected to the display screen, the power pad on the FPC is located above the light-emitting unit (lamp bead or pixel unit) relative to the display screen body 6, while the signal terminal pad 21 is close to the edge of the display screen glass circuit and below the light-emitting unit. At the same time, since the power terminals and signal terminals on the display screen are divided into two rows; in the traditional method The connector will block the light-emitting unit (display pixel point) between the power terminal and the signal terminal on the display screen, thereby forming a light-emitting blind area; by opening a through hole 23 corresponding to the row or column light-emitting unit (pixel unit) on the display screen on the substrate 1 of the connector, that is, a through hole 23 corresponding to the row or column light-emitting unit (pixel unit) on the display screen is opened between the signal terminal pad 21 and the power terminal pad 22 on the substrate 1, so that the light-emitting unit between the signal terminal pad 21 and the power terminal pad 22 on the display screen is not blocked, and further, the effective display area of ​​the display screen is increased, or the width of the black border on the side of the display screen is reduced.

By arranging the signal-end conductive contacts 31 and the power-end conductive contacts 32 in two rows, the width of the second connection area 3, that is, the width of the substrate 1 located there, can be reduced. Furthermore, the use of the signal-end conductive contacts 31 and the plurality of power-end conductive contacts 32 can facilitate the convenient connection of the display screen with the external control circuit board, such as plugging. Furthermore, multiple conductive circuits 4 are laid on the substrate 1, and each signal terminal pad 21 is electrically connected to the signal terminal conductive contact 31 through the conductive circuit 4, and each power terminal pad 22 is electrically connected to the power terminal conductive contact 32 through the circuit 4; wherein the conductive circuit 4 is a copper foil laid on the surface of the substrate 1.

Since the substrate 1 in this embodiment is a flexible substrate 1, such as an FPC substrate, it is relatively soft and not easy to plug it with the control circuit board, and a structural reinforcement is added. The structural reinforcement in this embodiment is hard plastic, so that it is easy to plug the connector with the external control circuit board.

Specifically, when the display screen and the pads of the connector are connected through the terminal post, the wiring can pass through the via 24 and then perform soldering; when the display screen and the pads of the connector are also connected through the pads, the solder can flow during soldering and form a connection through the via 24 and the pads on the display screen. The substrate 1 is made of a flexible material, and the width of the first connection area 2 is greater than the width of the second connection area 3.
