Problems solved by technology
Such a design leads to a reduction in the surface strength of the entire display product. In order to pursue folding performance, the drop-ball test of the module cannot reach the level of the glass cover module.
In addition, display products include integrated circuit chips (IC), and the surface of the display product will undergo large deformation during the pressing and folding process of the reliability test. IC is a rigid material and is prone to breakage when it is squeezed by external force.
[0003] To sum up, flexible display products in the prior art are prone to IC breakage due to stress, which affects product yield and product life.

The present application discloses a display device and an assembly method thereof, which are used to prevent the driving chip from breaking due to force. A display device provided by an embodiment of the present application includes: a display panel; the display panel is divided into a display area and a peripheral area located outside the display area; the peripheral area includes: a binding area, and a display area located between the binding area and the display area The bending area; the bending area is bent along the bending axis at the back of the display panel, so that the binding area is located at the back of the display panel; the display device also includes: located away from the The back side of the display panel and the driver chip bound in the binding area, and the protective cover of the driving chip; the protective cover includes: at least one on the side of the binding area away from the driving chip A first rigid spacer, a flat part opposite to the driving chip, and a supporting part connecting the first rigid spacer and the flat part; there is a gap between the flat part and the driving chip.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a display device and an assembly method thereof. Background technique [0002] At present, the design of display products is gradually developing towards the foldable direction. Due to the demand for folding performance, the material of the display product module is replaced with a flexible and foldable material. Such a design reduces the surface strength of the entire display product. In order to pursue folding performance, the drop-ball test of the module cannot reach the level of the glass cover module. In addition, display products include integrated circuit chips (IC), and the surface of the display product will undergo large deformation during the pressing and folding process, and the reliability test. IC is a rigid material, and it is easy to break when it is squeezed by external force. [0003] To sum up, the flexible display products in the prior art are pron...
