20200135135 | VOLTAGE SUPPLY UNIT AND METHOD, DISPLAY DRIVING CIRCUIT AND DISPLAY DEVICE - A voltage supply unit includes a control circuit, a capacitor circuit and a unidirectionally-conductive circuit. The control circuit controls an output end of the control circuit to be electrically connected to a first input end or a second input end of the control circuit under the control of a voltage signal from a first voltage output end. The capacitor circuit controls a potential at a first input end. When a difference between a first level and a potential at the first input end is greater than or equal to a predetermined on-state voltage, the unidirectionally-conductive circuit allows a unidirectional current flowing from a first level end to a first end thereof, and when the difference between the first level and the potential at the first input end is smaller than the predetermined on-state voltage, controls the first level end to be electrically disconnected from the first input end. | 2020-04-30 |
20200135136 | DISPLAY DEVICE - When supply of power has stopped, voltages of GDM signals are set as follows. A clear signal that contributes to removal of charge at floating nodes (an output control node and a stabilization node) in each unit circuit included in a shift register is set to a voltage of ground, and other signals (a gate start pulse signal, gate clock signals, and a reference voltage) are set to a gate-on voltage. To implement such settings, a single power supply system configuration that uses a voltage of only one channel as a scanning line selection voltage is adopted. | 2020-04-30 |
