Problems solved by technology

Although the color filter method has the disadvantage that the light utilization rate decreases due to the color filter absorbing light, resulting in high power consumption, the side-by-side selective deposition method can easily have a wider color gamut due to its high color purity, And because it can have high light utilization efficiency without color filters, the side-by-side selective deposition method is widely used
However, in this method, since the use of B2 (dark blue) is extremely limited, the light-emitting area always shifts, causing major problems in display quality such as deterioration of color mixing property and generation of color fringes even in normal white display

Abstract

The invention relates to an electro-optical device, an electrical device and a pixel rendering method. The electro-optical device has a pixel array composed of pixels arranged in a matrix. Each pixel includes four sub-pixels. The four sub-pixels include RGB sub-pixels and sub-pixels of similar colors of specified colors in RGB. List. In each pixel, the first sub-pixel with the highest luminance and the second sub-pixel with the second highest luminance among the sub-pixels required to display white are arranged on one diagonal line of the pixel, and the other sub-pixels are arranged on the other. on the diagonal. The electro-optical device has a control unit that switches between a first driving condition that causes a sub-pixel of a specified color and a sub-pixel of a similar color to be driven, depending on the color of a pixel to be displayed, and a second driving condition that Light is emitted at the first luminance ratio, and the second driving condition causes the sub-pixels of the specified color and the sub-pixels of the similar color to be driven to emit light at the second luminance ratio.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Patent Application No. 2015-031466 filed in Japan on February 20, 2015, the entire contents of which are incorporated herein by reference. technical field [0003] The invention relates to an electro-optical device, an electrical device and a pixel rendering method. More specifically, the present invention relates to an electro-optical device including a pixel array provided with pixels composed of sub-pixels of four colors or more, an electric device using the electro-optical device as a display device, and a pixel rendering method. Background technique [0004] Since the organic electroluminescent (EL) element is a current-driven self-luminous element, it does not require a backlight, and it has the advantages of low power consumption, large viewing angle, high contrast, etc.; it is highly anticipated in the development of flat panel displays . [0005] In an organic EL displa...
