DISPLAY MODULE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18154364 titled 'DISPLAY MODULE

Simplified Explanation

The abstract describes a display module that includes a display panel and a driving unit. The driving unit applies control signals to sub-pixels in a row-line order to set the PWM data voltage and control the light emission of the sub-pixels. The sub-pixels emit light for a time corresponding to the PWM data voltage set by the first control signal during the image frame period, and do not emit light for a preset time between consecutive image frame periods.

  • The display module includes a display panel and a driving unit.
  • The driving unit applies a first control signal to set the PWM data voltage of sub-pixels in a row-line order.
  • The driving unit applies a second control signal to control the light emission of sub-pixels in a row-line order.
  • The sub-pixels emit light for a time corresponding to the PWM data voltage set by the first control signal during the image frame period.
  • The sub-pixels do not emit light for a preset time based on the second control signal in the period between consecutive image frame periods.

Potential Applications

  • This display module can be used in various electronic devices such as smartphones, tablets, televisions, and computer monitors.
  • It can be applied in virtual reality (VR) and augmented reality (AR) devices to enhance the visual experience.
  • The technology can be utilized in automotive displays to provide clear and vibrant visuals.

Problems Solved

  • The technology solves the problem of power consumption in display modules by controlling the light emission of sub-pixels during idle periods.
  • It addresses the issue of image retention or burn-in by allowing sub-pixels to rest and not emit light for a preset time between consecutive image frame periods.

Benefits

  • The display module reduces power consumption, leading to improved energy efficiency and longer battery life in portable devices.
  • It helps prevent image retention or burn-in, prolonging the lifespan of the display panel.
  • The technology enhances the overall visual quality and clarity of displayed images.


Original Abstract Submitted

A display module comprises: a display panel; and a driving unit configured to apply a first control signal for setting a PWM data voltage to sub-pixels, included in each row-line of the display panel for each image frame, to the sub-pixels in a row-line order, and apply a second control signal for controlling the light emission of sub-pixels, included in each row-line, to the sub-pixel in a row-line order, wherein the sub-pixels included in each row-line emit light for a time corresponding to the PWM data voltage set according to the first control signal, based on the second control signal applied to the light emission section corresponding to the image frame, and do not emit light for a preset time based on second control signal applied in a period between consecutive image frame periods.
