Title:
SCAN CIRCUIT, DISPLAY SUBSTRATE, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/230835
Kind Code:
A1
Abstract:
A scan circuit having a plurality of stages is provided. A respective stage includes a respective scan unit configured to provide a control signal to at least a row of subpixels. The respective scan unit includes an input subcircuit (Isc) configured to receive a start signal (STV) or an output signal (G_(n-1)) from a previous scan unit, a first processing subcircuit (Psc1), a second processing subcircuit (Psc2), and an output subcircuit (Osc). The output subcircuit (Osc) includes a first output transistor (To1). The input subcircuit (Isc) includes a first input transistor (Ti1) and a second input transistor (Ti2) sequentially coupled between an input terminal (TMi) and a first node (N1). The first node (N1) is coupled to a gate electrode of the first output transistor (To1). The first processing subcircuit (Psc1) includes a first switch transistor (Ts1) and a second switch transistor (Ts2) coupled between the first node (N1) and a first reference terminal (TMr1). The first reference terminal (TMr1) is configured to receive a first reference signal (VREF1).
