Abstract

Even when a display color temperature of a flat plane display apparatus is corrected, a total color representation number is not reduced.

In a flat plane display module, both a light conducting plate and light emitting elements are fixed on a printed board. Furthermore, while a flat plane display apparatus is fixed on the light conducting plate, the respective light emitting elements, and the flat plane display apparatus are electrically connected to the printed board. The color temperature of the light emitting elements is changed by a circuit provided on the printed board so as to control the display color of the flat plane display apparatus. As a result, the display color of the flat plane display apparatus can be changed by the color temperature of the lighting, and the display color temperature of the flat plane display apparatus is corrected.

Claims

1. A display color temperature corrected lighting apparatus comprising:

a lighting apparatus which is added to either a front surface or a rear surface of a flat plane display apparatus;

wherein the lighting apparatus changes a color temperature,

a display temperare of the flat plane display apparatus is corrected by changing a color temperature of a lighting apparatus.

2. A flat plane display apparatus comprising:

a display temperature corrected lighting apparatus;

wherein the display temperature corrected lighting apparatus corrects a display color temperature of a flat plane display element by changing a color temperature of a lighting apparatus.

3. A flat plane display apparatus as claimed in claim 2, wherein the lighting apparatus corrects the color temperature by lighting made of three RGB colors.

4. A flat plane display apparatus as claimed in claim 2, wherein the lighting apparatus includes a light emitting element made of three RGB colors.

5. A flat plane display apparatus as claimed in claim 4, wherein the lighting apparatus color-temperature-corrects white liquid crystal by using a light emitting element made of three RGB colors.

6. A flat plane display apparatus as claimed in claim 4, wherein the light emitting element is arranged on a side surface of a light conducting plate.

7. A flat plane display apparatus as claimed in claim 6, wherein in the lighting apparatus, one set of light emitting elements made of three RGB colors is constituted by closely combining the light emitting elements in a serial manner on the side surface of the light conducting plate, and plural sets of light emitting elements are repeatedly arranged in a serial manner.

8. A flat plane display apparatus as claimed in claim 6, wherein in the lighting apparatus, one set of light emitting elements made of three RGB colors is constituted by closely combining the light emitting elements on the side surface of the light conducting plate at each of vertexes of a triangle, and the one set of light emitting elements is arranged in such a manner that the one set is alternately and repeatedly arranged in the triangular manner and the inverse-triangular manner.

9. A flat plane display apparatus as claimed in claim 3, wherein the lighting apparatus includes a reflection plate on a side surface of the light conducting plate, and conducts light made of three RGB colors emitted outside the lighting apparatus to the light conducting plate.
