Abstract
The embodiment of the invention discloses a display mother board and a preparation method of a display panel. The display mother board comprises an organic light-emitting display array mother board and a cover plate mother board, the organic light-emitting display array mother board comprises a plurality of organic light-emitting display panel areas, and each organic light-emitting display panel area comprises a display area and a peripheral area. A plurality of glass cement packaging structures are arranged between the organic light-emitting display array mother board and the cover plate mother board, a glass cement connecting part is arranged between the glass cement packaging structures corresponding to every two adjacent organic light-emitting display panel areas, and the adjacent glass cement packaging structures and the glass cement connecting parts between the adjacent glass cement packaging structures are connected into an integrated structure. The cover plate mother board is provided with a plurality of shading strips, the vertical projections of the shading strips on the cover plate mother board are located in the vertical projections of the glass cement connecting partson the cover plate mother board, and the vertical projections of cutting lines on the cover plate mother board are located in the vertical projections of the shading strips on the cover plate mother board. By adopting the technical scheme, the frame of the display panel can be reduced.
Description
technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to a display motherboard and a method for preparing a display panel. Background technique [0002] Organic light-emitting display panels are widely used in various high-performance display fields due to their advantages of high brightness, low power consumption, wide viewing angle, high response speed, and wide operating temperature range. [0003] However, water vapor and oxygen in the surrounding environment seriously affect the lifetime of the OLED panel. Therefore, it is necessary to package the organic light emitting display panel. In the prior art, due to the existence of the packaging structure, it is not conducive to the narrow frame design of the organic light emitting display panel, and at the same time, it will cause a low utilization rate of the substrate of the display motherboard. Contents of the invention [0004] In view of this, an emb...
