[0010] refer to image 3 , this pixel structure contains only three primary colors 35, 45 and 55, so a flat display device with this pixel structure cannot be used as a multi-channel display with three or more channels to widen the color range
[0011] Therefore, this flat display device cannot avoid color fringing errors, and cannot be used as a multi-channel display

Embodiment approach 1
[0025] Figure 4 A pixel structure according to a first embodiment of the present invention is shown. exist Figure 4 In , reference numeral 40 represents the first pixel representing the smallest unit of an image.
[0026] refer to Figure 4 , the structure of the first pixel 40 is hexagonal, and includes first to sixth sub-pixels 40a, 40b, 40c, 40d, 40e and 40f. The first to third sub-pixels 40a, 40b and 40c respectively display red (R), green (G) and blue (B), and the fourth to sixth sub-pixels 40d, 40e and 40f also display R, G and blue respectively. b.
[0027] That is, the first pixel 40 includes two sets of three sub-pixels displaying R, G, and B colors, and the sub-pixels are arranged in a counterclockwise direction.
[0028] The second pixel 42 adjacent to the first pixel 40 on the left side of the first pixel 40 has the same structure as the first pixel 40 . Therefore, like the sub-pixels 40a, . . . , 40f of the first pixel 40, the first to sixth sub-pixels 42a...
Embodiment approach 2
[0038] In the pixel structure according to the second embodiment of the present invention, each pixel forms a hexagon as in the pixel structure according to the first embodiment of the present invention. However, the pixels contain more primary colors than the pixels in the first embodiment.
[0039] In more detail, refer to Figure 5 , the first pixel 50 includes first to sixth sub-pixels 50a, 50b, 50c, 50d, 50e and 50f arranged counterclockwise. However, the sub-pixels 50a to 50f may be arranged in a clockwise direction. The first to sixth sub-pixels 50a, ..., 50f can display colors that can be combined to display white, such as red (R), green (G), blue (B), magenta (M), cyan (C) And yellow (Y). The pixels surrounding the first pixel 50 also have the same structure as the first pixel 50 . Numbers 4, 5 and 6 denote M, C and Y colors, respectively.
[0040] As described above, since the first pixel 50 includes six sub-pixels and the sub-pixels display colors different fro...

Abstract
The present invention provides a pixel structure for a flat panel display apparatus displaying images using a plurality of pixels, each of the pixels including six or more sub-pixels. The flat panel display apparatus including the pixel structure is free from a color fringe error, and the pixel can include three or more primary colors. Thus, a color representation range of the flat panel display apparatus can be widened. In addition, since the sub-pixels of the pixel can be controlled by sub-pixel rendering, a resolution of the apparatus can be improved. Moreover, high resolution can be obtained in every direction on the display due to superior rotational symmetry of the pixels.
Description
technical field [0001] The present invention relates to a plane display device, in particular to a pixel structure for the plane display device. Background technique [0002] Sub-pixel rendering is a technique for displaying images by directly and independently controlling the red (R), green (G) and blue (B) sub-pixels that form a pixel. When sub-pixel rendering is used to drive a flat display device, the spatial resolution of the flat display device can be improved. [0003] However, color fringing errors may occur when sub-pixel rendering techniques are applied to drive flat panel display devices. This error is caused by the pixel structure of the flat display device. Therefore, various pixel structures have been proposed to solve this problem. [0004] Figures 1 to 3 An example of a conventional pixel structure for a flat display device is shown. [0005] figure 1 Indicates a pixel structure widely used at present. In the stripe pattern, on...
