Problems solved by technology

However, it can be seen from the above driving principle that the increase in the number of pixel units will inevitably increase the number of sub-pixels, and the number of data lines driving the sub-pixels will also increase accordingly, which improves the resolution on the one hand, but reduces the aperture ratio on the other hand. The aperture ratio is also an important factor affecting the display effect.

Abstract

The invention provides a display substrate, a display device and a driving method thereof, and relates to the field of display technology. The display device has a relatively high resolution and a relatively high aperture ratio. A display substrate includes a plurality of pixel units arranged in an array, and each pixel unit includes at least R sub-pixels, G sub-pixels and B sub-pixels; the R sub-pixels, G sub-pixels and B sub-pixels of each row of pixel units are all connected to The first scanning line is connected; the R sub-pixel and the B sub-pixel in each row of pixel units are connected to a first data line, and the first data line is used to provide the R signal to the R sub-pixel in the first time period, and in the second The B signal is provided to the B sub-pixel in two time periods; the G sub-pixel of each row of pixel units is connected to a second data line, and the second data line is used to provide G to the G sub-pixel in the first time period and the second time period Signal; the first time period and the second time period are different time periods. Used in the manufacture of display substrates and display devices including the display substrates.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display substrate, a display device and a driving method thereof. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) displays have been widely used in the field of display technology. At present, high-definition and high-resolution display products have become the main development trend. [0003] refer to figure 1 As shown, an OLED display panel generally includes a plurality of scanning lines 1, a plurality of data lines 2 crossing the plurality of scanning lines 1, and a plurality of sub-pixels 3 arranged in a matrix, wherein each sub-pixel 3 is connected to a scanning line 1, A data line 2 is connected. The driving principle of the display panel is as follows: in one scanning period, one scanning line inputs scanning signals to the sub-pixels located in the same row, and multiple data lines input different data signals...
