Description

Display module, preparation method thereof and display device Technical Field The embodiment of the application relates to the technical field of display, in particular to a display module, a preparation method thereof and a display device. Background With the continuous development of consumer electronics, terminal devices such as mobile phones and tablet computers are evolving towards thinner, lighter and narrower frames. The display module is used as one of the core components of the terminal equipment, and the frame width of the display module directly influences the screen occupation ratio and visual experience of the whole machine. The width control of the lower frame is particularly critical, and is a process bottleneck of the design of the extremely narrow frame.
