Liquid crystal display module with scattering material coating on upper surface portion of lamp

1. A liquid crystal display module device, comprising:

a lamp housing of a back light unit;

a plurality of lamps in the lamp housing of a back light unit, wherein each of the plurality of lamps includes a tube shape;

a diffusion plate disposed on the lamps, wherein lower and upper surfaces of the diffusion plate have a transparent resin film coated with light-diffusion material to uniformly generate light;

a diffusion film disposed on the diffusion plate to increase an efficiency of the light;

a dual brightness enhancement film disposed on the diffusion film to select one of P-polarized and S-polarized constituents from the light;

a plurality of reflection plates arranged on bottom and side surfaces of the lamp housing and corresponding to each lamp; and

a scattering material made of transparent material and wholly coated only on an upper surface portion of each of the lamps facing toward the diffusion plate to transmit and scatter the light from each of the lamps toward the diffusion plate wherein the upper surface portion is substantially half that of a whole surface of each of the lamps.

2. The device according to claim 1 , further comprising:

a liquid crystal display panel disposed on the at least one optical sheet.

3. The device according to claim 1 , wherein the scattering material includes at least one of titanium oxide (TiO2) and silicon dioxide (SiO2).

4. The device according to claim 1 , wherein each of the plurality of lamps include phosphor material along inner sidewalls of a glass tube.

5. A liquid crystal display module device, comprising:

a lamp housing of a back light unit;

a plurality of lamps in the lamp housing of a back light unit, wherein each of the plurality of lamps includes a tube shape;

a reflection plate disposed on bottom and side surfaces of the lamp housing;

a plurality of protrusions that projects from the bottom surface of the lamp housing having a gap between adjacent lamps;

a diffusion plate disposed on the lamps, wherein lower and upper surfaces of the diffusion plate have a transparent resin film coated with light-diffusion material to uniformly generate light;

a diffusion film on the diffusion plate to increase an efficiency of the light;

a dual brightness enhancement film on the diffusion film to select one of P-polarized and S-polarized constituents from the light;

a liquid crystal display panel disposed on the dual brightness enhancement film; and

a scattering material made of transparent material and wholly coated only on an upper surface portion of each lamp facing toward the diffusion plate to transmit and scatter the light from each of the lamps toward the diffusion plate wherein the upper surface portion is substantially half that of a whole surface of each of the lamps.

6. The device according to claim 5 , wherein the protrusions have one of triangular, semicircular, and polygonal shapes.
