Abstract

The present disclosure relates to the field of display technology, and in particular, to an array substrate, a driving method for the array substrate, and a display device. The array substrate may include: a plurality of pixel units arranged in an array, a readout line, a reset circuit, and a readout circuit, wherein the second terminal of the gate transistor in each pixel unit belonging to the same column is connected to at least two The reading lines are connected so that some of the pixel units are connected to the same reading line, and some of the pixel units are connected to other reading lines. For each column of pixel units, each of the reading lines is connected to the column of pixel units through switching elements respectively. The corresponding readout circuits are connected, and for each column of pixel units, each readout line is connected to the reset circuit through switch elements. The disclosure greatly improves the reading speed of the readout circuit, thereby greatly improving the working efficiency of the array substrate, and at the same time ensures the reading speed under the condition that the accumulation time is short.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to an array substrate, a driving method for the array substrate, and a display device. Background technique [0002] With the development of optical technology and semiconductor technology, flat panel displays represented by liquid crystal display (Liquid Crystal Display, LCD) and organic light emitting diode display (Organic Light Emitting Diode, OLED) have the advantages of light and thin, low energy consumption, fast response speed, color The characteristics of good purity and high contrast ratio occupy a dominant position in the display field. [0003] Currently, the array substrate is provided with a pixel detection circuit, and its location can be determined according to specific requirements. The pixel detection circuit can be a passive pixel detection circuit equipped with a photodiode, which can be applied in optical detection such as X-ray (X-ray computed t...
