Title:
ACTIVE MATRIX DISPLAY AND METHOD FOR COMPENSATING FOR THRESHOLD VOLTAGE IN ACTIVE MATRIX DISPLAY
Document Type and Number:
Japanese Patent JP2018141955
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for compensating for a threshold voltage in an active matrix display (200).SOLUTION: A display (200) includes a plurality of pixels (100), and each of the pixels includes a drive transistor (102) having a driver gate (104) and a calibration gate (106), a first data line (110) selectively connected to the driver gate (104), and a second data line (114) selectively connected to the calibration gate (106). The present method includes a step (402) of driving the display (200) in a calibration and measurement mode for measuring a threshold voltage of the pixels (100); the first data line is connected to the driver gate, and the second data line is connected to the calibration gate. A measurement signal is actively driven in one of the first and second data lines (110, 114), and a calibration signal is measured in the other of the first and second data lines (110, 114).SELECTED DRAWING: Figure 13
