Display apparatus and manufacturing method thereof
View Patent ↗A display apparatus includes a display panel and a light guide unit. The light guide unit includes a body portion and a support portion. The body portion includes a light outputting surface near the display panel, and the support portion is placed on the edge of the light outputting surface to support the display panel. The support portion has an inclined surface, and at least one groove is formed between the inclined surface and the display panel for accommodating glue that combines the display panel and the light guide unit. In addition to being disposed in the groove, glue may be further disposed in a gap between the display panel, a back bezel, and the light guide unit.
1. A display apparatus, comprising:
a display panel;
a light guide unit comprising a body portion and a support portion, the body portion having a light outputting surface near the display panel, the support portion being placed on an edge of the light outputting surface to support the display panel, the support portion having an inclined surface, and at least one groove being formed between the inclined surface and the display panel for accommodating glue that combines the display panel and the light guide unit.
2. The display apparatus of claim 1 , wherein an opening of the groove faces the outside of the display panel and the light guide unit.
3. The display apparatus of claim 1 , wherein the inclined surface and the display panel form an angle of 5 to 85 degrees.
4. The display apparatus of claim 1 , wherein the inclined surface is step-like.
5. The display apparatus of claim 1 , wherein the inclined surface is curved.
6. The display apparatus of claim 1 , further comprising a back bezel disposed at the outside of a rim of the display panel and the light guide unit, and the groove having an opening facing the back bezel.
7. The display apparatus of claim 6 , wherein the back bezel has at least one hole corresponding to the opening of the groove through which glue is filled into the groove.
8. The display apparatus of claim 6 , wherein the glue further extends to a gap among the display panel, the back bezel and the light guide unit.
9. The display apparatus of claim 1 , wherein the body portion and the support portion are integrally formed.
10. The display apparatus of claim 1 , wherein the support portion has a width between 0.1 and 10 mm.
11. The display apparatus of claim 1 , wherein the support portion is strip-like and disposed on at least two sides of the light outputting surface.
12. The display apparatus of claim 1 , further comprising at least one optical sheet disposed among the display panel, the support portion and the light outputting surface.
13. A manufacturing method for a display apparatus, comprising the steps of:
providing a display panel and a light guide unit, wherein the light guide unit comprises a body portion and a support portion, the body portion has a light outputting surface, the support portion is disposed on an edge of the light outputting surface, and the support portion has an inclined surface;
placing the support portion against the display panel to assemble the display panel and the light guide unit, wherein the inclined surface of the support portion and the display panel form at least one groove therebetween, and the groove has an opening facing the outside of the light guide unit and the display panel; and
filling glue into the groove to combine the display panel and the light guide unit.
14. The manufacturing method of claim 13 , further comprising a step of providing a back bezel that is disposed at the outside of a rim of the display panel and the light guide unit and has at least one hole corresponding to the opening, wherein the glue is filled into the groove through the hole to combine the display panel and the light guide unit.
15. The manufacturing method of claim 13 , wherein the glue is filled into the groove by dispensing.
16. A manufacturing method for a display apparatus, comprising the steps of:
providing a light guide unit and a back bezel encompassing the light guide unit, wherein the light guide unit comprises a body portion and a support portion, the body portion has a light outputting surface, and the support portion is disposed on an edge of the light outputting surface, and the support portion has an inclined surface facing outwards;
dispensing glue on a surface of the back bezel near the inclined surface; and
disposing a display panel on the support portion to combine the display panel and the light guide unit, wherein the inclined surface and the display panel form at least one groove therebetween, the groove has an opening facing the back bezel, and a portion of the glue dispensed on the back bezel is guided into the groove through the inclined surface.
17. The manufacturing method of claim 16 , wherein the glue is dispensed at a position higher than or even with the inclined surface.
18. The manufacturing method of claim 16 , wherein a portion of the glue exists in a gap between the display panel and the back bezel after combining the light guide unit and the display panel.
19. The manufacturing method of claim 16 , wherein a portion of the glue exists in a gap between the light guide unit and the back bezel after combining the light guide unit and the display panel.
