Embodiment Construction

[0028] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0029] image 3 is a schematic diagram illustrating a pixel arrangement structure of an organic light emitting diode (OLED) display device according to an embodiment of the present invention.

[0030] refer to image 3 , The OLED display device according to an embodiment of the present invention has a diamond-shaped pentile pixel arrangement structure configured as follows: red R sub-pixels, green G sub-pixels and blue B sub-pixels are arranged in a diamond pattern shape. The first basic pixel may include R sub-pixels and G sub-pixels, and the second basic pixel may include B sub-pixels and G sub-pixels. The G sub-pixel included in each basic pixel may have a smaller size than the R and B sub-pixels in consideration of brightness, color temperature, and the like.

[0031] Each of the R subpixel, the G subpixel, and the ...

Abstract

An organic light emitting diode (OLED) display device for supplying a data signal to a pentile pixel array to reduce power consumption is disclosed. A plurality of the same color of sub pixels are disposed in different pixel columns and different pixel rows in a pentile pixel array. In the display device, the (1-1)th sub pixel and the (1-1)th pixel circuit, and the (2-2)th sub pixel and the (2-2)th pixel circuit may share the second data line and have pixel arrangement structures that are right and left inverted based on the second data line. The (1-2)th sub pixel and the (1-2)th pixel circuit, and the (2-3)th sub pixel and the (2-3)th pixel circuit may share the third data line and have pixel arrangement structures that are right and left inverted based on the third data line. The (1-3)thsub pixel and the (1-3)thpixel circuit, and the (2-4)thsub pixel and the (2-4)thpixel circuit may share the fourth data line and have pixel arrangement structures that are right and left inverted based on the fourth data line.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2016-0175739 filed on December 21, 2016, which is hereby incorporated by reference as if fully set forth herein. technical field [0002] The present invention relates to an organic light emitting diode display device for efficiently providing data signals to an array of P pixels (hereinafter referred to as "pentile pixels") and reducing power consumption. Background technique [0003] Representative examples of the image display device include a liquid crystal display (LCD), an organic light emitting diode (OLED) display device, and the like. [0004] The OLED display device is configured in such a manner that a plurality of pixel structures are formed by arranging red sub-pixels, green sub-pixels, and blue sub-pixels in various shapes and arrangements using self-luminous OLED elements. Among them, it is known that, as figure 1 As shown in , the diamond-shaped pentile pixel arrangement structure...
