Seal for touch screen module, touch screen module, monitor and method for assembling monitor
Disclosed is a seal for a touch screen module, comprising: a first side configured to be disposed at least at an edge of the touch screen module; and a second side opposite to the first side; wherein the second side is configured such that an outer section of the second side is to be fitted with a housing in an interference fit manner and at least a portion of an inner section of the second side is to be fitted with the housing in a non-interference fit manner. Also disclosed are a touch screen module, a monitor and an assembling method. The seal not only can achieve a good sealing effect to prevent any undesired substances from being collected at the seal and entering the interior of the monitor, but also can prevent the transparent cover from falling off from the housing due to stress generated by the seal.
1. A touch display panel, comprising:
a touch screen module; and
a housing for holding the touch screen module,
wherein the touch screen module further comprises a transparent cover and a seal for the touch screen module, the seal comprising:
a first side configured to be disposed at least at an edge of the touch screen module; and
a second side opposite to the first side;
wherein the second side is configured such that an outer section of the second side is to be fitted with the housing in an interference fit manner and at least a portion of an inner section of the second side is to be fitted with the housing in a non-interference fit manner;
wherein an outer surface of the seal is flush with an outer surface of the housing in a fitted status;
wherein the seal is disposed at outer edge of the transparent cover, and a glue is applied between an inner side of the transparent cover and a corresponding portion of the housing; and
wherein the first side is configured in a form of L-shaped structure so as to form a step portion for supporting the transparent cover.
2. The touch display panel according to claim 1 , wherein:
the seal is elastic; and/or
the seal is made of silicon rubber.
3. The touch display panel according to claim 2 , wherein:
only the outer section of the second side is configured to be fitted with the housing in the interference fit manner; and/or
at least a portion of the inner section of the second side is configured to be fitted with the housing in a clearance fit manner.
4. The touch display panel according to claim 2 , wherein the first side is configured in a form of L-shaped structure so as to form a step portion for supporting a transparent cover of the touch screen module.
5. The touch display panel according to claim 2 , wherein at least one longitudinal curved segment of the seal is provided with a stress-releasing structure for releasing a stress generated herein in the fitted status.
6. The touch display panel according to claim 1 , wherein:
only the outer section of the second side is configured to be fitted with the housing in the interference fit manner; and/or
at least a portion of the inner section of the second side is configured to be fitted with the housing in a clearance fit manner.
7. The touch display panel according to claim 6 , wherein;
the outer section of the second side comprises a contact rim for sealing contact with the housing; and/or
the inner section of the second side is configured to be fitted with the housing in the clearance fit manner.
8. The touch display panel according to claim 7 , wherein the first side is configured in a form of L-shaped structure so as to form a step portion for supporting a transparent cover of the touch screen module.
9. The touch display panel according to claim 6 , wherein the first side is configured in a form of L-shaped structure so as to form a step portion for supporting a transparent cover of the touch screen module.
10. The touch display panel according to claim 1 , wherein:
a corner of the L-shaped structure is configured to be spaced from the transparent cover in a fitted status; and/or
the step portion is provided with a sealing portion for sealing contact with the transparent cover; and/or
the transparent cover is a glass cover.
11. The touch display panel according to claim 10 , wherein:
the sealing portion comprises at least one compressible protrusion; and/or
the step portion is provided with a stress-reducing structure for reducing a stress generated by the sealing portion in the fitted status.
12. The touch display panel according to claim 11 , wherein:
the compressible protrusion is configured as an arc-shaped protrusion; and/or
the stress-reducing structure comprises a recess adjacent to the sealing portion.
13. The touch display panel according to claim 12 , wherein:
the recess is disposed below the sealing portion; and/or
the recess is configured to have a semicircular cross-section.
14. The touch display panel according to claim 1 , wherein at least one longitudinal curved segment of the seal is provided with a stress-releasing structure for releasing a stress generated herein in the fitted status.
15. The touch display panel according to claim 14 , wherein:
the at least one longitudinal curved segment comprises a corner of the seal; and/or
the stress-releasing structure comprises at least one groove extending along a longitudinal direction of the seal.
16. The touch display panel according to claim 1 , wherein the touch screen module is a projected capacitive touch screen module.
17. A method for assembling the touch display panel according to claim 1 , comprising the following steps:
providing the touch screen module of the touch display panel according to claim 1 ;
heating the housing to expand;
fitting the expanded housing onto the touch screen module; and
cooling the housing.
