Title:
ELECTRONIC DEVICE AND METHOD FOR OPERATING SAME
Document Type and Number:
WIPO Patent Application WO/2024/025221
Kind Code:
A1
Abstract:
An electronic device according to an embodiment of the present disclosure may comprise a display portion comprising a display on which multiple pixels are disposed, a display driving circuit portion for driving the display, a processor operatively connected to the display driving circuit portion, and a memory operatively connected to the processor. The display may comprise a center portion, a peripheral portion spaced apart from the center portion, and a middle portion positioned between the center portion and the peripheral portion. The center portion, the middle portion, and the peripheral portion may comprise pixel driving circuits for driving light-emitting elements disposed on the multiple pixels. The pixel driving circuits may comprise at least one driving transistor for supplying the light-emitting elements with a voltage for driving the light-emitting elements, a memory in which gradation data is stored, a PWM signal outputting unit for outputting one of multiple pulse width modulation (PWM) signals according to the gradation data stored in the memory, and a PWM signal switch tuned on or off by a PWM signal so as to control output of the voltage for driving the light-emitting elements. A first memory disposed on a first pixel included in the center portion, a second memory disposed on a second pixel included in the middle portion, and a third memory disposed on a second pixel included in the peripheral portion may have bits formed differently. Various other embodiments are also possible.
