Embodiment Construction

[0034] At present, in the existing special-shaped display panels, such as figure 1 As shown, the IC chip 1 will be bound at the bottom of the lower frame, that is, the lower part of the non-display area in the display area, and the test pads 2 for display testing are respectively set on both sides of the IC chip, so that the occupied area of ​​the lower frame is The large space will compress the space occupied by the special-shaped display area adjacent to the lower frame, resulting in the failure of the special-shaped display area to achieve the desired shape, such as the inability to achieve a perfect circle shape, thus failing to meet customer requirements.

[0035] Aiming at the problem that the lower frame size of the special-shaped display panel in the prior art is relatively large, the embodiments of the present invention provide a special-shaped display panel, a manufacturing method thereof, and a special-shaped display device. In order to make the object, technical so...

Abstract

The invention discloses an irregularly-shaped display panel, a fabrication method and an irregularly-shaped display device. A space of a chip welding region in a non-display region is utilized, the chip welding region is used for welding a chip, a space of a region shielded by the chip in the non-display region is utilized, a display test bonding pad is arranged, display detection is performed onthe irregularly-shaped display region by the display test bonding pad arranged in the chip welding region before delivery of the irregularly-shaped display panel, the function of the display test bonding pad is completed already after test is qualified, the chip can be welded at the chip welding region, the chip welding region can be shielded by a welded chip, and the function of each component arranged at a lower frame cannot be affected. Compared with an existing low frame design mode, the display test bonding pad is arranged at the chip welding region, frames at two sides of the chip welding region can be compressed, so that the space occupied by the lower frame is relatively small, required appearance of the irregularly-shaped display region is enabled to be achieved, the client requirement is met.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a special-shaped display panel, a manufacturing method thereof and a special-shaped display device. Background technique [0002] At present, with the rapid development and popularization of Internet technology, wearable devices have increasingly entered people's daily life, and special-shaped display devices such as smart watches are particularly prominent. Traditional watches only play the role of timing and decoration, while the emerging special-shaped display devices not only have the function of traditional watches, but also realize functions such as voice calls, text messages, and map navigation. The realization of these functions is inseparable from the special-shaped display. A special-shaped display panel mounted on the device. [0003] The narrow frame design of a special-shaped display panel such as a circular display panel can improve the overall display effect. In...
