Embodiment Construction
[0034] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0035] figure 1 It is the large-size OLED pixel compensation circuit at the present stage. The label A in the figure shows the data line (Data Line), and the label B shows the sensing line (Sense Line). The basic principle of compensation is:
[0036] Initialization stage: Turn on the Scan and Sense switches, and the Data Line is given a known voltage V data , Sense Line given reset voltage V ref , and have V data >V ref ;
[0037] Charging stage: Turn on the Scan and Sense switches, because V data >V ref , the Driving TFT (TFT in the figure) is turned on to generate current through the Sense switch to the capacitance C of the Sense Line sense Charging, when the voltage of Sense Line (point S) is charged to V data -V th , the Driving TFT is cut ...
