no. 1 Embodiment approach

[0077] The first embodiment of the present invention will be described.

[0078] (overall composition)

[0079] FIG. 1 is a block diagram showing a schematic configuration of an image display device 100 according to the first embodiment. The image display device 100 mainly includes an image processing unit 10 , a data line driving circuit 21 , a scanning line driving circuit 22 , and a display unit 23 . The image display device 100 can be configured to display images in multiple colors. Specifically, the image display device 100 can be configured to display four colors of red, green, blue, and cyan (hereinafter also abbreviated as "R", "G", "B", and "C").

[0080] The image processing unit 10 includes an I / F control circuit 11 , a color conversion circuit 12 , a VRAM (video memory) 13 , an address control circuit 14 , a table storage memory 15 , and a gamma correction circuit 16 . The I / F control circuit 11 acquires image data and control commands from the outside (such as ...

no. 2 Embodiment approach

[0115] Next, a second embodiment of the present invention will be described. In the second embodiment, the multi-color configuration is different from that in the first embodiment. Specifically, the second embodiment differs from the first embodiment in that white (hereinafter also abbreviated as "W" or "Wh") is used instead of cyan. That is, colors are configured by RGBW. Also, in the second embodiment, an image display device having the same configuration as the above-described image display device 100 is used, and therefore description thereof will be omitted. In addition, in the "white" sub-pixel, a transparent resin layer is arranged instead of a colored layer.

[0116] FIG. 12 is a diagram showing an example of display characteristics of the display unit 23 in the second embodiment. Fig. 12(a) is a graph showing the spectral characteristics of the color filter 23c, the horizontal axis represents the wavelength (nm), and the vertical axis represents the transmittance (...

no. 3 Embodiment approach

[0130] Next, a third embodiment of the present invention will be described. Compared to the aforementioned first and second embodiments, the arrangement of the display pixels in the display unit 23 is arranged in stripes; in the third embodiment, the arrangement of the display pixels in the display unit (hereinafter , also known as "display pixel configuration".) Change from a striped configuration.

[0131] FIG. 17 is a block diagram showing a schematic configuration of an image display device 101 according to the third embodiment. This image display device 101 differs from the image display device 100 of the first embodiment (see FIG. 1 ) in that a resampling circuit 11a for an input signal is added, and the number of outputs of the data line drive circuit 21 is different. Therefore, the same components and signals are denoted by the same reference numerals, and their descriptions are omitted.

[0132] The resampling circuit 11a changes the number of resampling circuits in...

Abstract

An image display device displays an image by using a plurality of display pixels, each display pixel including four sub-pixels corresponding to different colors. The four sub-pixels forming each of the display pixels are located such that two sub-pixels having a smaller level of luminance are located at edges of the display pixel, each of the two sub-pixels being located at either edge of the display pixel, and such that two other sub-pixels are located at a central portion of the display pixel so that an absolute value of a difference between a luminance added value, which is a value obtained by adding luminance levels of one of the sub-pixels located at the edges of the display pixel and an adjacent pixel, and a luminance added value, which is a value obtained by adding luminance levels of the other sub-pixel located at the edge of the display pixel and an adjacent pixel, is reduced.

Description

technical field [0001] The present invention relates to an image display device, an electronic device and a pixel configuration design method. Background technique [0002] Conventionally, an image display device capable of displaying an image using four or more colors (hereinafter also referred to as "multi-color") is known. Here, "color" refers to a color that can be displayed by a sub-pixel which is the minimum unit of display, and is not limited to the three colors of red, green, and blue. The image display device described above can display various colors by combining the sub-pixels corresponding to the displays of different colors. For example, there is known an image display device that performs display in four colors of red, green, blue, and cyan (hereinafter, also simply referred to as “RGBC”). [0003] However, in the technique described above, sub-pixels corresponding to RGBC are arranged without sufficiently considering the impact on vision. Contents of the i...
