Display and a backlight module and a light source holder thereof

1. A light source holder, comprising:

a circuit substrate having an opening and a base surface;

wherein the light source holder effectively reduces light leakage, and the base surface and the opening are transitionally connected by a wave surface on an inner surface of the circuit substrate, an inner side of the wave surface having a cross section of a straight line connected between the base surface and the opening.

2. The holder of claim 1 , wherein the circuit substrate comprises:

a main part having a top surface and a recess, an intersection of the recess and the top surface defining the opening; and

a copper electroplated substrate disposed at a bottom of the main part for supporting at least one light source, an intersection of the recess and a top surface of the copper electroplated substrate defining the base surface.

3. The holder of claim 1 , wherein the opening has a size greater than the base surface.

4. The holder of claim 1 , wherein the base surface and the opening are transitionally connected by a straight line, which slants outwards from bottom to top.

5. The holder of claim 2 , wherein the main part comprises Polycyclohexylenedimethylene Terephthalate/glass fiber (PCT/GF).

6. The holder of claim 3 , wherein an area ratio of the opening to the base surface is 1.77-1.88.

7. A backlight module, comprising:

a light guide panel; and

a backlight source, which emits light entering the light guide panel via a light receiving surface on a side of the light guide panel, the backlight source including a base plate and a plurality of light source holders disposed on the base plate;

wherein the light source holder includes:

a circuit substrate having an opening and a base surface;

wherein the light source holder effectively reduces light leakage, and the base surface and the opening are transitionally connected by a wave surface on an inner surface of the circuit substrate, an inner side of the wave surface having a cross section of a straight line connected between the base surface and the opening.

8. The module of claim 7 , wherein the circuit substrate comprises:

a main part having a top surface and a recess, an intersection of the recess and the top surface defining the opening; and

a copper electroplated substrate disposed at a bottom of the main part for supporting at least one light source, an intersection of the recess and a top surface of the copper electroplated substrate defining the base surface.

9. The module of claim 8 , wherein the light source comprises a light-emitting diode.

10. A display, comprising:

a display panel;

a light guide panel; and

a backlight source, which emits light entering the light guide panel via a light receiving surface on a side of the light guide panel for providing backlight for the display panel, the backlight source including a base plate and a plurality of light source holders disposed on the base plate;

wherein the light source holder includes:

a circuit substrate having an opening and a base surface;

wherein the light source holder effectively reduces light leakage, and the base surface and the opening are transitionally connected by a wave surface on an inner surface of the circuit substrate, an inner side of the wave surface having a cross section of a straight line connected between the base surface and the opening.

11. The display of claim 10 , wherein the circuit substrate comprises:

a main part having a top surface and a recess, an intersection of the recess and the top surface defining the opening; and

a copper electroplated substrate disposed at a bottom of the main part for supporting at least one light source, an intersection of the recess and a top surface of the copper electroplated substrate defining the base surface.
