Curved display panel manufacturing method and thermosetting device

Abstract

The invention provides a manufacture method of a curved surface display panel and a heat curing device. A bearing platform (22) is arranged in a heat curing furnace (21), and a plurality of oil paths (23) are arranged in the bearing platform (22); while the heat curing furnace (21) is used for heating to perform heat curing treatment on frame sealing glue (13) of a plane display panel (1), heat conduction oil (24) is made to flow cyclically in the oil paths (23) in the bearing platform (22); a CF substrate (12) of the plane display panel (1) is cooled, the temperature of the CF substrate (12) is kept lower than that of a TFT array substrate (11) to form a temperature difference between the TFT array substrate (11) and the CF substrate (12), and then outward stress is generated in the CF substrate (12). In this way, after the plane display panel is bent, inward shrinkage stress generated due to bending of the CF substrate can be offset, and the problems of bubbles and uneven brightness caused by the inward shrinkage stress of the CF substrate after the plane display panel is bent are avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing a curved display panel and a thermosetting device. Background technique [0002] A liquid crystal display (LCD, Liquid Crystal Display) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Such as: LCD TV, mobile phone, personal digital assistant (PDA), digital camera, computer panel screen or notebook computer panel screen, etc. [0003] In recent years, with the development of liquid crystal display technology, major manufacturers have successively launched curved liquid crystal display devices such as curved TVs. Overall, curved liquid crystal display devices can provide the best viewing effect from the center to the edge of the panel screen, while ordinary The presentation ability of the liquid crystal display device at the edge of the panel screen has been relatively unsatisfactory. The curved design...

Problems solved by technology

[0005] like figure 1 As shown, if there is no stress in the bending process of the display panel, then the bending of the CF substrate 100 and the TFT array substrate 200 are relatively uniform; but the actual situation is as follows figure 2 As shown, the CF substrate 100 and the TFT array substrate 200 are pasted and sealed by the sealant 300, so after the display panel is bent, the CF substrate 100 has a large shrinkage stress, and the bending is uneven, which will cause bubbles. and brightness unevenness (Mura)
