Illuminating device and liquid crystal display comprising same
In a direct backlight, a substrate on which LEDs are provided includes a plurality of module substrates. Each module substrate can be reduced in warping or deformation after a blanking process. In addition, each module substrate can be formed thin since bending due to its own weight is small. Consequently, the substrate as a whole and the backlight can be formed thin.
1. An illuminating device, comprising:
a substrate;
a plurality of LEDs mounted on the substrate; and
a control unit arranged to control driving of the LEDs; wherein
the substrate includes a plurality of module substrates;
the module substrates are provided with cut portions arranged to connect connectors to the module substrates, the connectors connecting the LEDs to the control unit; and
the cut portions are through holes.
2. The illuminating device of claim 1 , wherein the plurality of module substrates are arranged in a plurality of lines and columns.
3. An illuminating device, comprising:
a substrate;
a plurality of LEDs mounted on the substrate;
a control unit arranged to control driving of the LEDs; and
a housing arranged to fix the substrate; wherein
the substrate includes a plurality of module substrates;
the LEDs mounted on the substrate are fitted into holes formed in a bottom of the housing;
an inclined surface that is disposed around each of the holes is provided in a surface of a bottom of the housing that is opposite to a surface of the bottom of the housing that faces the substrate; and
a thermal conductive member made of rubber is provided on a surface of the substrate that is opposite to a surface of the substrate that faces the bottom of the housing.
4. The illuminating device of claim 3 , wherein a reflective material is provided on the surface of the bottom of the housing that is opposite to the surface thereof that faces the substrate.
5. A liquid crystal display, comprising:
a liquid crystal panel; and
the illuminating device of claim 1 that is disposed behind the liquid crystal panel.
6. The illuminating device of claim 3 , wherein the plurality of module substrates are arranged in a plurality of lines and columns.
7. The illuminating device of claim 3 , wherein a cut portion is formed in each of the module substrates for connecting a connector thereto, the connector connecting the LEDs to the control unit.
8. A liquid crystal display, comprising:
a liquid crystal panel; and
the illuminating device of claim 3 that is disposed behind the liquid crystal panel.
