Abstract

The invention provides an array substrate, a display device and an electronic device, belonging to the display field. The array substrate is provided with a plurality of sub pixels arranged into a matrix, a plurality of scanning lines and a plurality of data lines, one scanning line is arranged between the two adjacent rows of sub pixels, each row of sub pixels correspond to one scanning line, each sub pixel comprises a charging TFT (thin-film transistor) electrically connected with the scanning line corresponding to the row of sub pixels, and a pixel electrode corresponding to the charging TFT, wherein each sub pixel further comprises a precharging TFT and a pixel electrode corresponding to the precharging TFT, and the precharging TFT is electrically connected with the scanning line corresponding to the superiorprevious row of sub pixels. According to the technical scheme, the array substrate can meet the charging rate requirement of the sub pixels can be met under the condition of not influencing the display effect.

Description

technical field [0001] The present invention relates to the display field, in particular to an array substrate, a display device, and an electronic device. Background technique [0002] At present, large-size TV products and 3D products are the development trend in the display field. However, in order to realize the development of large-size TV products and 3D products, the problem of shortening the charging time caused by high-frequency driving must be solved. If the driving frequency of the product is increased from 60Hz to 120Hz or even 240Hz, the charging time for each sub-pixel will be shortened to 1 / 2 or even 1 / 4 of the original, which will have a serious impact on the charging rate of the sub-pixel . [0003] At present, in order to ensure the charging rate of the sub-pixel, the usual solution is to increase the W / L (width-to-length ratio) of the channel to increase the charging current value (I on ), so that the target charging rate can be achieved while the chargi...
