Description

Technical Field

[0001] The utility model belongs to the technical field of home appliance display screens, and particularly relates to a curved ultra-thin display module, a curved combined display panel and a home appliance. Background Art

[0002] Home appliance display panels are the control modules of home appliances, providing control, display, and operation functions. As consumers' demand for displays increases, display panels are developing towards ultra-thin, large-screen displays, and space-saving features. However, the structure and shape of the control panels vary greatly for different home appliance designs. In order to adapt to different functions, usage scenarios, or industrial shape designs, the design of the display module needs to be adjusted and new technical problems brought about by the implementation of the new design need to be solved accordingly.

[0003] For a home appliance panel with a curved surface, including mechanical knobs, a thick lamp cavity display unit, a power switch, and a digital tube, and requiring a portion of the panel to have an ultra-thin, large-background display module, the following issues need to be addressed in order to integrate these various designs on the same display panel:

[0004] (1) The upper surface of the display panel is curved, and the ultra-thin large background display module uses touch to realize key operation. There is a requirement for the distance between the outer surface of the panel and the touch circuit board. Too large a distance will result in a weak touch signal. Therefore, it is necessary to solve the problem of minimizing the distance between the ultra-thin large background display module and the panel while being able to be designed together with the thicker mechanical knob and the thicker lamp cavity display unit on the same display bracket.

[0005] (2) Since the panel is curved, with the middle higher and the sides lower, the ultra-thin display module uses the structure of side-lighting and light guide plate to achieve uniform illumination and light. The ultra-thin display module is tightly attached to the upper cover panel to form a seamless state so that the touch signal transmission is stable and the sensitivity is high. For this reason, each individual light guide plate will have different thicknesses, which makes assembly difficult. There are a large number of light guide plates, which are easily installed in the wrong position and the assembly time is long. Utility Model Content
