摘要: A voltage providing circuit includes a first voltage output end, a temperature-sensitive element, a power supply circuit and an output circuit. The power supply circuit is configured to apply a control voltage signal to a control end of the temperature-sensitive element. The temperature-sensitive element is configured to, under the control of the control voltage signal, generate a temperature-related voltage, and output the temperature-related voltage via a first end of the temperature-sensitive element, and a value of the temperature-related voltage changes along with an ambient temperature of the temperature-sensitive element. The output circuit is configured to output a temperature-adaptive voltage via the first voltage output end. A difference between a value of the temperature-adaptive voltage and the value of the temperature-related voltage is within a predetermined range.

摘要: The present application discloses a circuit for providing a temperature-dependent common electrode voltage. The circuit includes a sensing sub-circuit coupled between a power-supply terminal and a ground terminal and configured to generate a first voltage for controlling a switching sub-circuit to connect the power-supply terminal to a first node. The circuit further includes a compensation sub-circuit coupled between the first node and the ground terminal and be enabled, when the first voltage decreases below a threshold as temperature increases above a threshold temperature, to output a temperature-dependent second voltage proportional to the temperature to a second node. Additionally, the circuit includes an output sub-circuit coupled to the second node combined with a first input-voltage terminal and further coupled to a second input-voltage terminal, to generate a temperature-dependent output voltage based on a weighted mixing of the temperature-dependent second voltage, a first input voltage, and a second input voltage.

摘要: The present disclosure relates to the field of display technology, and in particular, to a pixel driving circuit, a pixel driving method, and a display apparatus. The pixel driving circuit includes: a first input device, a second input device, a driving transistor, a compensation sub-circuit, an isolation device, a reset device, and an energy storage device. The disclosure can eliminate the influence of the threshold voltage of the driving transistor and the voltage drop of the wire due to impedance on the driving current, ensuring that the driving currents output by the pixel driving circuits are uniform, thereby ensuring the uniformity of the display brightnesses of the pixel units, and furthermore, the first pole of the light-emitting device is reset to eliminate the influence of the signal of previous frame.
