Abstract

The invention discloses a driving circuit and a driving method of a display array, relates to the field of display technology, and satisfies the display requirement of high resolution. The driving circuit of the display array includes m rows×n columns of pixel driving units. Each pixel driving unit includes a plurality of gray scale control periods in one driving cycle. The pixel driving unit includes: a gate transistor, a first driving transistor, a storage capacitor and a light emitting circuit. Wherein: the gate transistor is electrically connected to the control terminal of the first drive transistor and the storage capacitor respectively. Each gate transistor is used to write m data signals into each storage capacitor in one-to-one correspondence under the control of m row scan signals in each gray scale control period. The first electrode of the first driving transistor is electrically connected to the light emitting circuit. The second electrode of the first driving transistor is grounded. Each first driving transistor is used to control the operation of each light emitting circuit under the control of m data signals in each gray scale control period.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a driving circuit and a driving method of a display array. Background technique [0002] The driving circuit of the existing display array adopts the method of controlling the light emission of pixels in each row at different periods after the scanning and gating stage, so as to realize the control of the pixel array. However, the way of controlling light emission at different time periods will result in low scanning efficiency and cannot realize high-resolution display driving. Contents of the invention [0003] The purpose of the present invention is to provide a driving circuit and a driving method of a display array, which adopts a driving method in which the light-emitting circuits of each row emit light at the same time, so as to meet the display requirement of high resolution. [0004] In order to achieve the above object, the present invention provides a driving circu...
