Description

Technical Field

[0001] The utility model belongs to the technical field of control boxes, and specifically relates to a control box, a display module and an electrical appliance device. Background Art

[0002] For some electrical appliance devices such as washing machines, the outer shape structure of the display screen needs to be adapted to the outer shape of the device, resulting in a relatively large distance between the display screen and the internal display board. For relatively small display icons on the display screen, due to the long distance from the LED lamp beads on the display board, they cannot be effectively displayed, resulting in problems such as the overall dimness of the icons and incomplete display of the icons. To effectively display smaller icons, one solution is to make a digital tube separately on the circuit board. However, the cost of the digital tube is relatively high, and a separate injection mold for manufacturing the digital tube is required, resulting in an increase in the cost of the display module.

[0003] Therefore, there is an urgent need for a solution to solve the problem that relatively small display icons on electrical appliance devices in the prior art cannot be effectively displayed without adding digital tubes. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a control box, a display module and an electrical appliance device, which can solve the problem that relatively small display icons on electrical appliance devices in the prior art cannot be effectively displayed under the condition of controlling costs.
