Description

Technical Field

[0001] The present invention belongs to the technical field of home appliance display screens, and in particular relates to an arc-shaped combined display panel, a combination method and a home appliance. Background Art

[0002] The home appliance display panel is the control module of the home appliance, which has functions such as control, display, and operation. As consumers' demand for display increases, display panels are developing in the direction of ultra-thin, large-screen display, and space saving. However, for different styles of home appliance designs, the structure and shape of the control panel are very different. In order to adapt to different functions, usage scenarios or industrial shape designs, it is necessary to adjust the design of the display module and solve new technical problems brought about by the implementation of the new design.

[0003] For a display panel design with a curved surface, including mechanical knobs, thick lamp cavity display units, power switches, digital tubes, etc., and requiring some home appliance panels with ultra-thin large background display modules, in order to integrate various designs on the same display panel, the following problems need to be solved:

[0004] (1) The upper surface of the display panel is curved, and the ultra-thin large background display module realizes key operation through touch control. 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, high in the middle and low on both sides, the ultra-thin display module uses the structure of side-lighting and light guide plate to achieve uniform light emission 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 take a long time to assemble. Summary of the invention

[0006] The technical problem solved by the present invention is to provide a combined curved ultra-thin display module, display panel and home appliance which are sensitive to touch, save time and effort in assembly, have a high accuracy rate and can meet the requirements of a large height difference.
