Abstract

A system for displaying images is provided. The system includes a display device including a display device having a pixel unit array. Each pixel unit is constituted by a first sub-pixel and a second sub-pixel adjoined thereto. The first sub-pixel includes a plurality of first charged colored particles and a plurality of second charged colored particles to receive a light source that doesn'"'"'t pass through a color filter. The second sub-pixel includes a plurality of third charged colored particles and a plurality of fourth charged colored particles to receive the light source. The pluralities of first, second, third, and fourth charged colored particles have at least three colors in total.

Claims

1. A system for displaying images, comprising:

a display device having a pixel unit array, wherein each pixel unit is constituted by a first sub-pixel and a second sub-pixel adjoined thereto,

wherein the first sub-pixel comprises a plurality of first charged colored particles and a plurality of second charged colored particles to receive a light source that doesn'"'"'t pass through a color filter and the second sub-pixel comprises a plurality of third charged colored particles and a plurality of fourth charged colored particles to receive the light source, and

wherein the pluralities of first, second, third, and fourth charged colored particles have at least three colors in total.

2. The system of claim 1, wherein the plurality of first charged colored particles has a color which is the same as that of the plurality of third charged colored particles and different from the plurality of fourth charged colored particles, while the plurality of second charged colored particles has a color different from that of the pluralities of third and fourth charged colored particles.

3. The system of claim 2, wherein the plurality of first, second or third charged colored particles has a color of red, green, blue, magenta, cyan or yellow.

4. The system of claim 1, wherein the first and second sub-pixels respectively comprises an electrophoretic display layer comprising solvent, liquid, or air, such that the pluralities of first, second, third, and fourth charged colored particles are in the corresponding electrophoretic display layers.

5. The system of claim 4, wherein the display device further comprises a reflection layer disposed under the electrophoretic display layers to reflect the light source.

6. The system of claim 1, wherein the pluralities of first, second, third, and fourth charged colored particles comprise dye or pigment, respectively.

7. The system as claimed in claim 1, further comprising:

a flat panel display comprising the display device; and

an input unit coupled to the flat panel display and operative to provide input singles to the flat panel display, such that the flat panel display displays images.

8. The system of claim 7, wherein the system comprises an electronic device comprising the flat panel display.

9. The system of claim 8, wherein the electronic device is a projector, an electronic book, a laptop computer, a mobile phone, a digital camera, a personal digital assistant, a desktop computer, a television, a car display or a portable DVD player.

10. A system for displaying images, comprising:

a display device having a pixel unit array, wherein each pixel unit is constituted by a single sub-pixel,

wherein the sub-pixel comprises a plurality of first charged colored particles, a plurality of second charged colored particles, and a plurality of third charged colored particles to receive a light source that doesn'"'"'t pass through a color filter, and

wherein the pluralities of first, second, and third charged colored particles have different colors from each other.

11. The system of claim 10, wherein the sub-pixel further comprises a plurality of fourth charged colored particles having a color different from that of the pluralities of first, second, and third charged colored particles.

12. The system of claim 11, wherein the plurality of fourth charged colored particles has a color of red, green, blue, magenta, cyan or yellow.

13. The system of claim 11, wherein the pluralities of first, second, third, and fourth charged colored particles comprise dye or pigment, respectively.

14. The system of claim 10, wherein the sub-pixel comprises an electrophoretic display layer comprising solvent, liquid, or air, such that the pluralities of first, second, and third charged colored particles are in the electrophoretic display layer.

15. The system of claim 14, wherein the display device further comprises a reflection layer disposed under the electrophoretic display layer to reflect the light source.

16. The system of claim 10, wherein the pluralities of first, second, and third charged colored particles comprise dye or pigment, respectively.

17. The system as claimed in claim 10, further comprising:

a flat panel display comprising the display device; and

an input unit coupled to the flat panel display and operative to provide input singles to the flat panel display, such that the flat panel display displays images.

18. The system of claim 17, wherein the system comprises an electronic device comprising the flat panel display.

19. The system of claim 18, wherein the electronic device is a projector, an electronic book, a laptop computer, a mobile phone, a digital camera, a personal digital assistant, a desktop computer, a television, a car display or a portable DVD player.
