Problems solved by technology

However, there are still some shortcomings in the current display device. For example, the known process still cannot make the pixel units of the same display panel have exactly the same characteristics, so there are differences between the pixel units arranged in different positions or driven by different chips. The driving effect, so the driving current / voltage required by each pixel unit is different
However, the different driving currents / voltages required by the pixel units will lead to uneven brightness among the pixel units during driving, resulting in color shift, and the viewers will feel the above shortcomings more clearly under the low-brightness display screen.

Embodiment Construction

[0034] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

[0035] Please refer to figure 1 , figure 1 It is a schematic diagram of an embodiment of a display device 100 , for example, the display device 100 is an active organic light emitting display device (Active Martix Organic Light Emitting Display, AMOLED). The display device 100 includes a data driver 10 , a gate driver 20 and a plurality of pixels 30 , and each pixel 30 includes a plurality of sub-pixels 31 . In this embodiment, each pixel 30 includes four sub-pixels 31 , but not limited thereto. Each sub-pixel 31 is individually electrically coupled to the data driver 10 through the data line DL and electrically coupled to the gate driver 20 through the gate line GL. Multiple sub-pixels 31 in the same row are connected to the same data line DL is electrically coupled, and the plurality of sub-pixels 31 in the same column ar...

Abstract

A display device comprises a first pixel, a second pixel, and a data driver. The first pixel correspondingly displays a first group of grayscale data, the second pixel is adjacent to the first pixel and forms a pixel group with the first pixel, and the second pixel corresponds to a second group of grayscale data. The data driver is electrically coupled to the first pixel and the second pixel, and the data driver is configured to determine whether to make the first pixel and the second pixel emit light according to the first group of grayscale data and the second group of grayscale data.

Description

technical field [0001] The invention relates to a display device, in particular to a display device capable of improving color shift and a driving method thereof. Background technique [0002] Currently, display devices are widely used in various fields to display images, such as smart phones, tablet computers, or televisions. Wherein, the display device includes a display panel, and the display panel includes a plurality of pixel units, and the display device enables the display panel to display images by driving the plurality of pixel units. However, there are still some shortcomings in the current display device. For example, the known process still cannot make the pixel units of the same display panel have exactly the same characteristics, so there are differences between the pixel units arranged in different positions or driven by different chips. Therefore, the driving current / voltage required by each pixel unit is different. However, the different driving currents / v...
