Patent ID: 10217411

Abstract:
Disclosed are a display driving circuit and a driving method thereof, and a display apparatus. The display driving circuit comprises a control unit (13), a light emitting device (20) and a collection unit (21). The collection unit (21) is connected with one terminal of the light emitting device (20), the control unit (13) and a collection signal input terminal (Fn) respectively, and is configured to collect brightness of the light emitting device (20) according to a signal input from the collection signal input terminal (Fn) and feed a collection result to the control unit (13); the control unit (13) is connected with the one terminal of the light emitting device (20) and the collection unit (21) respectively, and is configured to adjust an actual light emitting brightness value (L) of the light emitting device (20) to a target brightness value (D) according to the collection result; and the other terminal of the light emitting device (20) is connected with a first voltage (VSS), and is configured to emit light under the control of the control unit (13). The display driving circuit can bring uniformity of brightness in light emitted from respective pixel units.
