Abstract

A touch panel display device that is easily produced with a lower cost and has moisture-proof and dust-proof properties includes an upper casing, a lower casing, a touch control module and a circuit board. The upper casing includes a display part and a remaining part surrounding the display part. The lower casing is mounted corresponding to the upper casing to define a space therein. The touch control module is located under a bottom of the upper casing in the defined space. The circuit board is located between the touch control module and the lower casing in the defined space. The display part and the remaining part of the upper casing are integrally formed in a single body with no gap or slit there between. A bottom of the display part is correspondingly attached to a top of the touch control module.

Claims

1. A touch panel display device, comprising:

an upper casing being made of transparent material and including a display part and a remaining part surrounding the display part;

a lower casing, mounted corresponding to the upper casing to define a space therein;

a touch control module, located under a bottom of the upper casing in the defined space; and

a circuit board, located between the touch control module and the lower casing in the defined space,

wherein the display part and the remaining part of the upper casing are integrally formed in a single body with no gap or slit there between, and a bottom of the display part is correspondingly attached to a top of the touch control module.

2. The touch panel display device of claim 1, wherein the remaining part of the upper casing is further painted.

3. The touch panel display device of claim 2, wherein an exterior of the remaining part is painted.

4. The touch panel display device of claim 2, wherein both exterior and interior of the remaining part are painted.

5. The touch panel display device of claim 1, wherein the display part of the upper casing is further strengthened or tempered to provide improved wear resistance or shock resistance.

6. The touch panel display device of claim 1, wherein the display part of the upper casing is located at a level lower than the remaining part.

7. The touch panel display device of claim 6, wherein the remaining part of the upper casing is further painted.

8. The touch panel display device of claim 7, wherein an exterior of the remaining part is painted.

9. The touch panel display device of claim 7, wherein both exterior and interior of the remaining part are painted.

10. The touch panel display device of claim 6, wherein the display part of the upper casing is further strengthened or tempered to provide improved wear resistance or shock resistance.
