Problems solved by technology
Due to the large amount of heat generated during the laser cutting process, the heat will diffuse to the functional film layers related to the display and damage the functional layers, such as the electrical characteristics of the thin film transistor and the sealing effect of the thin film packaging layer, making the The functional layer is vulnerable to water and oxygen corrosion, resulting in abnormal display and shortened lifespan
Although the above problems can be solved by keeping the cutting area away from the functional layer related to the display, it will also bring about the problem of expanding the frame area, which does not conform to the development trend of narrow frame design

The invention provides a display panel, a display panel motherboard and a manufacturing method thereof. The display panel comprises a substrate comprising a display region and a frame region surrounding the display region; a display element arranged on the substrate and in the display region; and a heat-conductive pattern layer arranged in the frame region of the substrate, wherein at least a part of the heat-conductive pattern layer is embedded in the substrate, and the heat-conductive pattern layer surrounds the display region. In the cutting process of the display panel motherboard, the generated heat can be absorbed or exported by the heat-conductive pattern layer, so that damage to the display element and a film encapsulation layer can be reduced; and meanwhile, reduction of heat conduction and heat absorption performance due to melt and breakage of the heat-conductive pattern layer can be prevented, and thus heat conduction and heat absorption effects of the heat-conductive pattern layer are ensured, and cutting qualified rate is improved.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a display panel motherboard and a manufacturing method thereof. Background technique [0002] With the continuous development of display technology, the display panel manufacturing technology is becoming more and more mature. Existing display panels mainly include Organic Light Emitting Diode (OLED), Liquid Crystal Display (LCD), A plasma display panel (Plasma Display Panel, PDP) and the like. The flexible display panel is a deformable and bendable display device made of materials such as polyimide or polyester film. Compared with the traditional display panel, the flexible display panel has the advantages of small size, low power consumption, With the advantages of being bendable and flexible, it is a display panel with broad application prospects. [0003] The manufacturing process of the existing flexible display panel is usually as follows: a flexible subs...
