Abstract

A luminescent display device is disclosed. The luminescent display device is comprised of an array of pixels, a first driving chip and a second driving chip. The array of pixels is comprised of columns and rows of pixels. The first driving chip is connected a first pixel of the array of pixels, and the second driving chip is connected to a second pixel of the array of pixels. The second pixel is adjacent to the first pixel. The first driving chip is not connected to all pixels in a row of the at least one row of pixels.

Claims (43)

1. A luminescent display device comprising:

an array of pixels, wherein said array of pixels is comprised of at least one column of pixels and at least one row of pixels, each pixel including a light-emitting diode;

a first driving chip, wherein said first driving chip is connected to a first pixel of said array of pixels; and

a second driving chip, wherein said second driving chip is connected to a second pixel of said array of pixels, wherein said second pixel is adjacent to said first pixel, and said first pixel and said second pixel are located in a same column;

wherein said first driving chip is not connected to all pixels in said at least one row of pixels.

2. The luminescent display device of claim 1 , wherein said luminescent display device is a passive OLED panel.

3. The luminescent display device of claim 1 , wherein said luminescent display device is an active OLED panel.

4. A luminescent display device, comprising:

an array of pixels, wherein said array of pixels is comprised of at least two column of pixels and at least two row of pixels;

a first driving chip, wherein said first driving chip is connected to first and second pixels of said array of pixels; and

a second driving chip, where said second driving chip is connected to third and fourth pixels of said array of pixels;

wherein:

said first pixel is adjacent to said second pixel;

said third pixel is adjacent to said fourth pixel;

said second pixel is adjacent to said third pixel;

said second pixel is between said first pixel and said third pixel; and

said first driving chip is not connected to all pixels in at least one of said at least two rows of pixels.

5. The luminescent display device of claim 4 , wherein said first, second, third and fourth pixels are located in a same column.

6. The luminescent display device of claim 4 , wherein said first, second, third and fourth pixels are located in a same row.

7. The luminescent display device of claim 4 , wherein said luminescent display device is a passive OLED panel.

8. The luminescent display device of claim 4 , wherein said luminescent display device is an active OLED panel.

9. The luminescent display device of claim 4 , wherein said luminescent display device is an LED panel.

10. A luminescent display device, comprising:

an array of pixels, wherein said array of pixels is comprised of at least two columns of pixels and at least two rows of pixels;

a first driving chip, wherein said first driving chip is connected to first, second, third and fourth pixels of said array of pixels; and

a second driving chip, where said second driving chip is connected to fifth, sixth, seventh and eighth pixels of said array of pixels;

wherein:

said first pixel is adjacent to said second pixel;

said fifth pixel is adjacent to said sixth pixel;

said second pixel is adjacent to said fifth pixel;

said second pixel is between said first pixel and said fifth pixel;

said third pixel is adjacent to said fourth pixel;

said seventh pixel is adjacent to said eighth pixel;

said fourth pixel is adjacent to said seventh pixel;

said fourth pixel is between said third pixel and said seventh pixel; and

said first driving chip is not connected to all pixels in at least one of said at least two rows of pixels.

11. The luminescent display device of claim 10 , wherein said first, second, fifth and sixth pixels are located in a same column.

12. The luminescent display device of claim 10 , wherein said first, second, fifth and sixth pixels are located in a same row.

13. The luminescent display device of claim 10 , wherein said third, fourth, seventh and eighth pixels are located in a same column.

14. The luminescent display device of claim 10 , wherein said third, fourth, seventh, and eighth pixels are located in a same row.

15. The luminescent display device of claim 10 , wherein said luminescent display device is a passive OLED panel.

16. The luminescent display device of claim 10 , wherein said luminescent display device is an active OLED panel.

17. The luminescent display device of claim 10 , wherein said luminescent display device is an LED panel.
