Description

Technical Field

[0001] This utility model belongs to the field of display device technology, specifically relating to a waterproof display device with a sealing strip. Background Technology

[0002] In the production and application of home appliances, such as dishwashers, washing machines, tea bar machines, and coffee machines, which are located near water sources, waterproofing is a concern. If water gets into the circuit board or it becomes damp, it will affect the touch control and display. In severe cases, water can damage the electronic components, causing inconvenience to users and increasing repair costs.

[0003] For home appliance panels that include mechanical knobs, thick lamp cavity display units, power switches, digital tubes, etc., and require some ultra-thin large background display modules, it is necessary to combine components of different thicknesses into one display module when integrating various designs on the same display panel, and the parts in contact with the panel must be of uniform height.

[0004] The applicant's earlier invention patent application, publication number CN119132196A, entitled "An Arc-Shaped Combined Display Panel, Combination Method, and Home Appliance," discloses an arc-shaped combined display panel: including a display screen bracket and a panel. One side of the display screen bracket is a first structure for mounting an arc-shaped ultra-thin display module, wherein the arc-shaped ultra-thin display module is disposed. The other side of the display screen bracket is a second structure for a display control component with a thickness greater than that of the arc-shaped ultra-thin display module. The arc-shaped ultra-thin display module includes a first film, a light-blocking component, a light guide plate, and a first circuit board arranged sequentially from top to bottom. Multiple light guide plates are combined to form an arc shape corresponding to the shape of the panel. Each light guide plate is provided with a light guide plate positioning post and is coded, and the first circuit board is provided with a light guide plate positioning hole corresponding to the light guide plate positioning post.

[0005] However, when applying it to a washing machine, waterproofing needs to be considered. Since a bracket is used to combine two display modules of different thicknesses, the thicker display module can be easily waterproofed by applying glue to its back. However, in order to make the upper surface of the super-mode display module flush with the upper surface of the thicker display module, a bracket is used to raise the super-mode display module and embed it in the upper part of the bracket. Other components also need to be installed on the back of this part of the bracket. Therefore, the waterproofing problem of the super-mode display module needs to be solved. Utility Model Content

[0006] The technical problem solved by this utility model is to provide a waterproof display device with a sealing strip that has a good sealing effect.

[0033] For home appliance panels that include mechanical knobs, thick lamp cavity display units, power switches, digital tubes, etc., and require some ultra-thin large background display modules, it is necessary to combine components of different thicknesses into one display module when integrating various designs on the same display panel, and the parts in contact with the panel must be of uniform height.

[0034] In this embodiment, the display module adopts a combined display module, which includes a display module bracket 5. The display module bracket 5 is provided with a first display control component 30 and a second display control component 40 with a thickness greater than the first display control component 30. The first display control component 30 is an arc-shaped ultra-thin display module (which can be the arc-shaped ultra-thin display module disclosed in Chinese invention patent with publication number CN119132196A: an arc-shaped combined display panel, combination method and home appliance) or a flat ultra-thin display module (the flat ultra-thin display control module adopts an ultra-realistic ultra-thin display module with application number 202223539772.1). It is combined with the shape of the display module bracket 5 to form an arc-shaped combined display module or a flat combined display module.

[0035] The upper surface of panel component 2 is either flat or curved. The combined display module 1 is designed to match the shape of panel component 2, with its upper surface being either flat or curved.

[0036] For example, the curved combined display module uses a display module bracket 5 to combine display modules and components of different heights together. One side of the display module bracket 5 is provided with a curved first display control component 30, and the other side is provided with a second display control component 40 with a thickness greater than the curved first display control component 30. The upper surface of the display module bracket 5 can also be set as curved.
