Abstract:
1. A display device, comprising: a plurality of pixels, each storing voltage and displaying brightness according to the stored voltage, wherein each pixel comprises: a driving module updating the stored voltage during a frame period, wherein the frame period comprises a plurality of row times, each row time comprises at least one programming period and at least one emission period, the driving module de-activates the pixels to stop displaying brightness during the programming periods and activates the pixels to display brightness during the emission periods, wherein the driving unit is a first transistor, and the first transistor comprises a gate coupled to the second node, a source receiving the first operation voltage and a drain coupled to the luminescence unit, wherein the reset unit is a second transistor, and the second transistor comprises a gate receiving a reset signal, a drain receiving a reset level and a source coupled to the second node, wherein the switching unit is a third transistor, and the third transistor comprises a gate receiving a scan signal, a source coupled to the second node and a drain coupled to a drain of the first transistor, wherein a first programming period among the programming period comprises a reset write period and a detection period, wherein during the reset write period, the driving module provides a data signal to the first node and controls the reset signal to turn on the second transistor, wherein during the detection period, the driving module controls a level of the first node to be equal to a level of the data signal and controls the reset signal and the scan signal to turn off the second transistor and to turn on the third transistor, wherein during the emission period, the driving module provides a reference level to the first node and controls the reset signal and the scan signal to turn off the second and the third transistors, and wherein during the reset write period, the driving module controls the scan signal to turn on the third transistor.
