AI Technical Summary
Technical Problem
Existing display devices are prone to color shift defects at low grayscale levels.
Method used
By introducing control transistors into the pixels, the drive current flowing to the first and second emitter units can be controlled to be different in magnitude, thereby improving the color shift defect at low grayscale.
Benefits of technology
When driving at low grayscale, more driving current is applied to the second emission unit, reducing or preventing color shift defects and improving the display effect.
