Abstract

A display panel is provided. The display panel includes pixels that include a red (R) subpixel, a green (G) subpixel, a blue (B) subpixel, and a white (W) subpixel arranged in a first package and a second package disposed adjacent to the first package. The first package includes the B subpixel and the G subpixel and the second package includes the R subpixel and the W subpixel.

Claims (25)

1. A display panel comprising:

a plurality of pixels, each pixel comprising a first package and a second package disposed adjacent to the first package,

wherein the first package comprises a first plate on which a blue (B) subpixel and a green (G) subpixel are disposed, and the second package comprises second plate, different from the first plate, on which a red (R) subpixel and a white (W) subpixel are disposed.

2. The display panel of claim 1 , wherein a partition is disposed between the first package and the second package to prevent transmission of light emitted from the B subpixel and the G subpixel to the second package, and to prevent transmission of light emitted from the R subpixel and the W subpixel to the first package.

3. The display panel of claim 1 , wherein the W subpixel comprises a blue (B) subpixel covered by a yellow phosphor.

4. The display panel of claim 1 , wherein the R, G, B, and W subpixels are each implemented as a light emitting diode (LED).

5. A display apparatus comprising:

a display panel comprising a plurality of pixels, each pixel comprising a first package and a second package disposed adjacent to the first package, the first package comprising a first plate on which a blue(B) subpixel and a green(G) subpixel are disposed and the second package comprising second plate, different from the first plate, on which a red(R) subpixel and a white(W) subpixel are disposed;

a panel driver configured to drive the display panel;

a processor configured to, for each pixel, determine a W subpixel value by signal-processing R, G, B data for the pixel included in an inputted video signal, determine R, G, B subpixel values based on the determined W subpixel value, and control the panel driver so that the R, G, B, and W subpixels are turned on based on the determined R, G, B, and W subpixel values.

6. The display apparatus of claim 5 , wherein a partition is disposed between the first package and the second package to prevent transmission of a light emitted from the B subpixel and the G subpixel to the second package, and to prevent transmission of a light emitted from the R subpixel and the W subpixel to the first package.

7. The display apparatus of claim 5 , wherein the W subpixel comprises a blue (B) subpixel covered by a yellow phosphor.

8. The display apparatus of claim 5 , wherein the R, G, B, and W subpixels are each implemented as a light emitting diode (LED).

9. The display apparatus of claim 5 , wherein the processor performs, for each pixel, gamma conversion regarding R, G, B data, determines a W subpixel value based on the gamma-converted R, G, B data, and determines R, G, B subpixel values by performing inverse gamma conversion regarding a rest of the gamma-converted R, G, B data excluding the determined W subpixel value.

10. The display apparatus of claim 5 , wherein the processor controls the panel driver so that, in one video frame section, a plurality of subpixels are turned on as a preset group unit, and the subpixel groups arranged at a position shifted by a preset subpixel unit are sequentially turned on.

11. A controlling method of a display apparatus including a display panel including a plurality of pixels, each pixel comprising a first package and a second package disposed adjacent to the first package, the first package comprising a first plate on which a blue (B) subpixel and a green (G) subpixel are disposed, and the second package comprising a second plate, different from the first plate, on which a red (R) subpixel and a white (W) subpixel are disposed, the controlling method comprising:

determining, for each pixel, a W subpixel value by signal-processing R, G, B data included in an inputted video signal;

determining R, G, B subpixel values based on the determined W subpixel value; and

controlling so that R, G, B, and W subpixels are turned on based on the determined R, G, B, and W subpixel values.

12. The controlling method of claim 11 , wherein a partition is disposed between the first package and the second package to prevent transmission of a light emitted from the B subpixel and the G subpixel to the second package, and to prevent transmission of a light emitted from the R subpixel and the W subpixel to the first package.

13. The controlling method of claim 11 , wherein the W subpixel comprises a blue (B) subpixel covered by a yellow phosphor.

14. The controlling method of claim 11 , wherein the R, G, B, and W subpixels are each implemented as a light emitting diode (LED).

15. The controlling method of claim 11 , wherein the determining the W subpixel value comprises performing gamma conversion regarding R, G, B data, and determining the W subpixel value based on the gamma-converted R, G, B data.

16. The controlling method of claim 11 , wherein the determining the R, G, B subpixel values comprises determining R, G, B subpixel values by performing inverse gamma conversion regarding a rest of the gamma-converted R, G, B data excluding the determined W subpixel value.

17. The controlling method of claim 11 , further comprising controlling so that, in one video frame section, a plurality of pixels are turned on by a preset group unit, and the subpixel groups arranged at a position shifted by a preset subpixel unit are sequentially turned on.
