Problems solved by technology

The color filter method has the following disadvantages: Since the color filter absorbs light, light utilization efficiency decreases, resulting in increased power consumption, while the side-by-side selective coating method can easily have a wider color gamut due to its high color purity, and The side-by-side selective coating method is widely used due to the improvement of light utilization efficiency without using color filters
Therefore, the corrugated tile arrangement makes an otherwise smooth curve appear as a step-like jagged, or a defect in which color changes are observed as a line in an image that continuously changes in hue or brightness

Abstract

The invention relates to a pixel array, electro optical device, an electric apparatus and a method of driving the pixel array. In the pixel array, pixels are two-dimensionally arranged, each of the pixels including a subpixel of the first color having a highest luminosity factor, a subpixel of the second color and a subpixel of the third color having a lowest luminosity factor. A circuit element in each of subpixels of the first color to the third color in each of the pixels is arranged in a row direction. A light emitting region of a subpixel of the first color and a light emitting region of a subpixel of the second color are arranged in the first direction inclined to the row direction. A light emitting region of a subpixel of the third color is arranged in the second direction orthogonal to the first direction, with respect to the light emitting region of the subpixel of the first color and the light emitting region of the subpixel of the second color. The data line extends and is connected to circuit elements in the sub pixels. Data lines connected with the circuit elements in the first color and the light emitting region of the subpixel of the second color, data lines connected with the circuit elements in the second color and the light emitting region of the subpixel of the third color and data lines connected with the circuit elements in the third color and the light emitting region of the subpixel of the first color are arranged repeatedly.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Patent Application No. 2015-4706 filed in Japan on Jan. 14, 2015, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a pixel array, an electro-optical device including the pixel array, an electrical device using the electro-optical device as a display device, and a method of driving the pixel array. Background technique [0004] Since the organic electroluminescent (EL) element is a current-driven self-luminous element, it does not require a backlight, and can obtain advantages such as low power consumption, high viewing angle, and high contrast, and is highly anticipated in the development of flat panel displays. . [0005] In an organic EL display device using such an organic EL element, a large number of pixels are constituted by sub-pixels of different colors such as red (R), green (G), and blue (B), wh...
