Abstract

An LCD assembly used with a wireless information terminal including: an LCD module including an LCD and a TSP attached on a surface of the LCD; a housing having upper and lower housing members which butt against each other to be coupled in order to support the LCD module, an exposure window of a certain size being formed in the upper housing member; and a space maintaining member inserted to maintain a certain gap between a rim of the TSP of the LCD module and the upper housing member, and formed of a rubber material having excellent elasticity and impact-absorbing capacity. The space maintaining member has a fixture portion and a pad portion in close contact with the TSP, and the pad portion has an air groove allowing air to exist between the TSP and itself.

Claims

1. An LCD assembly used with a wireless information terminal, comprising:

an LCD module having an LCD and a touch screen panel (TSP) attached on a surface of the LCD;

a housing having upper and lower housing members which butt against each other to be coupled together in order to support the LCD module and an exposure window of a certain size being formed in the upper housing member; and

a waterproof space maintaining member inserted to maintain a certain gap between a rim of the TSP of the LCD module and the upper housing member.

2. The LCD assembly according to claim 1, wherein the space maintaining member is formed of a rubber material having excellent elasticity and impact-absorbing capacity.

3. The LCD assembly according to claim 1, wherein the space maintaining member has a fixture portion and a pad portion in close contact with the TSP, and the pad portion has an air groove allowing air to exist between the TSP and itself.

4. The LCD assembly according to claim 3, wherein the air groove is formed by a curvature molding allowing the pad portion to be slantedly declined toward both sides thereof from a center thereof.

5. The LCD assembly according to claim 3, wherein a fixture groove of a shape matching with the fixture portion in which the fixture portion is inserted is formed in the upper housing member to fix the space maintaining member.

6. An LCD assembly used with a wireless information terminal, comprising:

an LCD module having an LCD and a touch screen panel (TSP) attached on a surface of the LCD;

a housing having upper and lower housing members which butt against each other to be coupled in order to support the LCD module and an exposure window of a certain size being formed in the upper housing member; and

a space maintaining member inserted to maintain a certain gap between a rim of the TSP of the LCD module and the upper housing member, the space maintaining member being incorporated with the upper housing member into one body by a double injection molding.

7. The LCD assembly according to claim 6, wherein the space maintaining member is formed of a rubber material having excellent elasticity and impact-absorbing capacity.

8. The LCD assembly according to claim 6, wherein a part of the space maintaining member contacting with the TSP has an air groove internally recessed to allow air to exist between the part and the TSP.
