DISPLAY MODULE AND DRIVING METHOD OF DISPLAY MODULE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17957824 titled 'DISPLAY MODULE AND DRIVING METHOD OF DISPLAY MODULE
Simplified Explanation
The abstract describes a display module with pixels that have subpixels of different colors arranged in a matrix form. Each subpixel includes an inorganic light emitting element, a constant current generator, and a pulse width modulation (PWM) circuit. The PWM circuit controls the time during which the constant current flows through the inorganic light emitting element based on a PWM data voltage and a threshold voltage of a driving transistor.
- The display module has pixels with subpixels of different colors arranged in a matrix form.
- Each subpixel includes an inorganic light emitting element, a constant current generator, and a pulse width modulation (PWM) circuit.

Original Abstract Submitted
A display module may include a plurality of pixels, wherein each of the plurality of pixels includes a plurality of subpixels of different colors that are disposed in a matrix form. Each of the plurality of subpixels includes an inorganic light emitting element, a constant current generator which provides a constant current to the inorganic light emitting element, and a pulse width modulation (PWM) circuit which includes a first depletion mode driving transistor, and controls a time during which the constant current flows through the inorganic light emitting element based on a PWM data voltage applied to a gate terminal of the first depletion mode driving transistor and a threshold voltage of the first depletion mode driving transistor.
