Abstract

A liquid crystal display module includes: a liquid crystal display panel, a surface light-emitting lamp irradiating light to the liquid crystal display panel by a surface light-emission, and a power source supplying an electric power to the surface light-emitting lamp. The surface light-emitting lamp includes a frame having a light-emitting space, a first barrier rib formed partitioning the lamp into light-emitting spaces, electrode pairs, and a second barrier rib defining a light-emitting path for each of the partitioned light-emitting spaces.

Claims (26)

1. A liquid crystal display module comprising:

a liquid crystal display panel;

a surface light-emitting lamp irradiating light to the liquid crystal display panel by a surface light-emission; and

a power source supplying an electric power to the surface light-emitting lamp,

wherein the surface light-emitting lamp includes:

a frame having a light-emitting space;

a plurality of first barrier ribs formed within the frame and partitioning the light-emitting space into a plurality of partitioned light-emitting spaces;

a plurality of electrode pairs for producing electric fields in each of the partitioned light-emitting spaces, respectively; and

a plurality of second barrier ribs defining a light-emitting path of each of the partitioned light-emitting spaces,

wherein each of the partitioned light-emitting spaces is completely closed owing to the surrounding of the first barrier ribs and the second barrier ribs.

2. The liquid crystal display module according to claim 1 , which further comprises a transparent substrate arranged on the frame.

3. The liquid crystal display module according to claim 1 , wherein an inert gas fills the partitioned light-emitting spaces.

4. The liquid crystal display module according to claim 1 , wherein a phosphor is applied to an inside wall of each of the partitioned light-emitting spaces.

5. The liquid crystal display module according to claim 1 , wherein the power source includes a plurality of the power sources, each of which supplies the electric power to each of the electrode pairs, respectively.

6. The liquid crystal display module according to claim 1 , wherein the power source commonly supplies the electric power to the electrode pairs.

7. A surface light-emitting lamp for a display, which comprises:

a frame having a light-emitting space;

a plurality of first barrier ribs formed within the frame and partitioning the light-emitting space into a plurality of partitioned light-emitting spaces;

a plurality of electrode pairs for producing electric fields in each of the partitioned light-emitting spaces, respectively; and

a plurality of second barrier ribs defining a light-emitting path of each of the partitioned light-emitting spaces,

wherein each of the partitioned light-emitting spaces is completely closed owing to the surrounding of the first barrier ribs and the second barrier ribs.

8. The surface light-emitting lamp according to claim 7 , which further comprises a transparent substrate arranged on the frame.

9. The surface light-emitting lamp according to claim 7 , wherein an inert gas fills the partitioned light-emitting spaces.

10. The surface light-emitting lamp according to claim 7 , wherein a phosphor is applied to an inside wall of each of the partitioned light-emitting spaces.

11. The surface light-emitting lamp according to claim 7 , which further comprises a power source, wherein the power source includes a plurality of the power sources, each of which supplies the electric power to each of the electrode pairs, respectively.

12. The surface light-emitting lamp according to claim 7 , which further comprises a power source, wherein the power source commonly supplies the electric power to the electrode pairs.
