Problems solved by technology

The organic light-emitting display panel has no backlight module, so the overall strength is weak. In order to enhance the strength of the organic light-emitting display panel, an attachment component will be installed on the back of the organic light-emitting display panel to enhance the strength of the panel. At the same time, the flexibility is realized through the attachment component. The grounding of the circuit board, the attachment component and the flexible circuit board are connected to the ground part manually. However, there are a large number of device blocks distributed on the flexible circuit board. When the alignment is inaccurate, it is easy to cover the ground part on the attachment component. The device area of ​​the flexible circuit board, resulting in abnormal display

Abstract

The embodiment of the invention provides a display device, and relates to the technical field of display. According to the display device, a flexible circuit board and an attaching assembly can achieve alignment more accurately, so that display anomaly caused by inaccurate alignment is reduced. The display device comprises an organic light-emitting display panel, the flexible circuit board connected to the organic light-emitting display panel, and the attaching assembly attached to the organic light-emitting display panel, wherein the flexible circuit board comprises an attaching part, and theattaching part comprises a first grounding area; the attaching assembly comprises a second grounding area corresponding to the first grounding area; the attaching part is located between the attaching assembly and the organic light-emitting display panel; the first grounding area and the second grounding area are overlapped, and an alignment mark is arranged on the side, away from the organic light-emitting display panel, of the attaching part in the first grounding area; a hollowed-out area corresponding to the alignment mark is arranged on the portion, in the second grounding area, of the attaching assembly.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] At present, display technology has penetrated into every aspect of people's daily life, and correspondingly, more and more materials and technologies are used in display screens. Currently, mainstream display screens mainly include liquid crystal display screens and organic light-emitting display panels. Among them, due to the self-luminous performance of the organic light-emitting display panel, compared with the liquid crystal display panel, the most energy-consuming backlight module is omitted, so it has the advantage of being more energy-saving. [0003] An organic light emitting display panel, a main board and a flexible circuit board form a display device, the main board is arranged on the back of the organic light emitting display panel, and the flexible circuit board is used to realize the signal connection between...
