Embodiment 1
[0054] like image 3 As shown, the structure of an active electroluminescent display is basically composed of a pixel array part Pixel, a scan driver Scan, a data input driver DATA, and a data input driver ba. The pixel array components are connected to the scan lines SCAN arranged in rows, the first data signal lines and the second data signal lines arranged in columns, and the pixel array components also include a plurality of power lines for providing the necessary power for the pixel operation. Low-potential power supply VSS and high-potential power supply VDD. The first data signal line required for the operation of the pixel is used to control the pulse width of the PWM signal, the second data signal line is used to control the output current of the current source, the low-potential power supply VSS is also used for grounding, and the high-potential power supply VDD is used to supply the The pixel provides power supply, the first data signal line is the output of the da...
Embodiment 2
[0083] like image 3 As shown, the structure of the active electroluminescent display of this embodiment 2 basically consists of a pixel array component Pixel, a scan driver Scan, a data input driver DATA, and a data input driver ba. The pixel array components are all connected to the scan lines SCAN arranged in rows, the first data signal lines and the second signal data lines arranged in columns, and the pixel array components also include a plurality of power lines for providing the necessary power for the pixel operation. Low-potential power supply VSS and high-potential power supply VDD. The first data signal line required for the operation of the pixel is used to control the pulse width of the PWM signal, the second data signal line is used to control the output current of the current source, the low-potential power supply VSS is also used for grounding, and the high-potential power supply VDD is used to supply the The pixel provides the power supply.
