DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/253486
Kind Code:
A1
Abstract:
A display apparatus, comprising: a plurality of scanning lines (21); a gate driving circuit (30), which is electrically connected to the plurality of scanning lines (21); and a timing controller (40), which is electrically connected to the gate driving circuit (30), and is configured to receive a plurality of data enable signals (DE) within each of a plurality of frame periods, generate gate control signals according to the data enable signals (DE) and provide the gate control signals for the gate driving circuit (30). The gate driving circuit (30) is configured to provide scanning signals for the plurality of scanning lines (21) according to the gate control signals. The gate control signals comprise a start signal (STV), a first clock signal (CKV1) and a second clock signal (CKV2). Each frame period comprises an active period (V-avtive) and a vertical blanking period (V-blanking), and the data enable signals (DE) are only within the active period (V-avtive). The timing controller (40) generates a rising edge of the start signal (STV) within a vertical blanking period (V-blanking) of an (N-1)th frame period, and a time interval between a falling edge of the last data enable signal (DE) within the (N-1)th frame period and the rising edge of the start signal (STV) is T, wherein T is greater than 0 and less than a first preset time interval or T is greater than 0 and equal to the first preset time interval, and the first preset time interval is less than 2/3 of the vertical blanking period (V-blanking); or the timing controller (40) generates the rising edge and a falling edge of the start signal (STV) in a formation time interval of a rising edge and a falling edge of the first data enable signal (DE) within an Nth frame period, wherein N ≥ 2.
