Backlight assembly for liquid crystal display and liquid crystal display module using the same
View Patent ↗A backlight assembly for a liquid crystal display includes a lamp to irradiate light; a light guide plate to guide incident light from the lamp to a display panel; a plurality of optical sheets disposed in front of the light guide plate, and each optical sheet having an eye part with a through-hole; a guide panel to house the lamp, and having a jaw-like step part to mount the light guide plate and the optical sheets; and an adhesive pad having a lower end that passes through the through-hole and provided on the guide panel, and an upper end that adheres to the display panel.
1. A backlight assembly for a liquid crystal display, the assembly comprising:
a lamp to irradiate light;
a light guide plate to guide incident light from the lamp to a display panel;
a plurality of optical sheets disposed in front of the light guide plate, and each optical sheet having an eye part with a through-hole;
a guide panel to house the lamp, and having a jaw-like step part to mount the light guide plate and the optical sheets; and
an adhesive pad having a lower end that passes through the through-hole and provided on the guide panel, and an upper end that adheres to the display panel.
2. The assembly of claim 1 , further comprising a reflecting plate to reflect light emitted from the light guide plate.
3. The assembly of claim 1 , wherein the adhesive pad is formed of silicon.
4. The assembly of claim 3 , wherein the adhesive pad comprises:
a cup shaped body that adheres to the display panel; and
a support supporting the body that fixes to the guide panel.
5. The assembly of claim 4 , wherein the guide panel has an insertion groove where the support passing through the through-hole is inserted and fixed.
6. A liquid crystal display module, comprising:
a liquid crystal panel positioned front side of the module to output an image;
a lamp to irradiate light to the liquid crystal panel;
a light guide plate to guide incident light from the lamp to the liquid crystal panel;
a plurality of optical sheets disposed in front of the light guide plate, each optical sheet having an eye part with a through-hole;
a guide panel to house the lamp and having a jaw-like step part to mount the light guide plate and the optical sheets;
an adhesive pad having a lower end that passes through the through-hole and provided on the guide panel, and an upper end that adheres to the liquid crystal panel to prevent shifting of the liquid crystal panel;
a bottom cover to mount the guide panel, wherein the light guide plate, the optical sheets, and the liquid crystal panel are sequentially mounted on the guide panel; and
a top cover to cover edges of the front surface of the liquid crystal panel and a side of the guide panel.
7. The module of claim 6 , wherein the adhesive pad is formed of silicon.
8. The module of claim 6 , wherein the adhesive pad comprises:
a body having a cup shape; and
a support to support the body.
9. The module of claim 8 , wherein the guide panel has an insertion groove where the support passing through the through-hole is inserted and fixed.
10. The module of claim 8 , wherein the jaw-like step part of the guide panel comprises:
a first mounting surface to mount the light guide plate; and
a second mounting surface to mount the optical sheets.
11. The module of claim 10 , wherein the second mounting surface has an insertion groove.
12. The module of claim 6 , wherein the adhesive pad is provided at least two at two sides of the optical sheets that faces each other.
13. The module of claim 6 , wherein the adhesive pad is provided at least one at each side of the optical sheets.
