Liquid crystal display with point illuminator bonded to liquid crystal panel thereof
View Patent ↗An exemplary liquid crystal display includes a liquid crystal panel, a light guide plate, and a point illuminator. The liquid crystal panel includes a first substrate, a second substrate, and a liquid crystal layer disposed between the first and second substrates. The light guide plate is disposed on a side of the second substrate that is not in contact with the liquid crystal layer, and includes a light incident surface. The point illuminator is rigidly bonded to the side of the second substrate that is not in contact with the liquid crystal layer, and faces the light incident surface of the light guide plate, such that the position of the point illuminator is fixed relative to the light guide plate.

2. The liquid crystal display of claim 1 , wherein the second substrate comprises an extension portion arranged at an edge thereof, and the extension portion is not covered by the liquid crystal layer or the first substrate.
3. The liquid crystal display of claim 2 , wherein the extension portion comprises a conductive pad formed on an outer surface thereof that is not in contact with the liquid crystal layer.
4. The liquid crystal display of claim 3 , wherein the point illuminator is directly bonded to the conductive pad by the ACF.
5. The liquid crystal display of claim 3 , further comprising an optical film disposed between the light guide plate and the liquid crystal panel wherein a thickness of the conductive pad matches a thickness of the optical film.
6. The liquid crystal display of claim 1 , wherein the point illuminator is a light emitting diode (LED).
7. The liquid crystal display of claim 1 , wherein the second substrate is rigid.
8. A liquid crystal display comprising:
a liquid crystal panel comprising an upper substrate, a lower substrate, and a liquid crystal layer disposed between the upper and the lower substrates, the lower substrate including an extension portion at one edge thereof, the extension portion including a metal pad;
a light guide plate disposed on a side of the lower substrate; and
a point illuminator directly fixed to the metal pad and being adjacent to the light guide plate such that the position of the point illuminator is fixed relative to the light guide plate, wherein the point illuminator and the light guide plate cooperatively provide uniform light beams for the liquid crystal panel.
9. The liquid crystal display of claim 8 , wherein the point illuminator is directly fixed to the metal pad by an anisotropic conductive film (ACF).
10. A liquid crystal display comprising:
a point illuminator;
a liquid crystal panel comprising a first substrate, a second substrate, and a liquid crystal layer disposed between the first and second substrates, the second substrate comprising an inner surface and an outer surface at opposite sides thereof, with the inner surface being adjacent and opposite to the first substrate; and
a light guide plate adjacent to the outer surface of the second substrate;
wherein the point illuminator is directly mounted on the second substrate and is adjacent to the light guide plate such that the position of the point illuminator is fixed relative to the light guide plate, and the point illuminator and the light guide plate cooperatively provide uniform light beams for the liquid crystal panel.
