Display driver system with embedded non-volatile memory

A circuitry for adjusting image data to-be rendered on a display device, comprising:

• a non-volatile memory, comprising a plurality of memory cells configured to store luminance correction data and deburn-in correction data of the display device;
• a luminance adjusting circuit configured to receive the luminance correction data from the non-volatile memory array and adjust the image data based on the luminance correction data;
• and
• a deburn-in circuit configured to receive the deburn-in correction data from the non-volatile memory array and dynamically adjust pixel output of the image data to compensate for darkening or discoloration.

A circuitry in an electronic device supporting an always-on-display (AOD) mode, comprising:

• a screen;
• a non-volatile memory array (NVM) configured to store AOD information being displayed on the display panel in the AOD mode, wherein the AOD information comprises static content to be displayed during the AOD mode;
• a random-access memory (RAM) configured to receive image data to be displayed on the screen in a non-AOD mode;
• one or more processors;
• and
• a memory storing instructions which, when executed by the one or more processors, cause the circuitry to:
• selectively activate a subset of the plurality of pixels on the display panel based on the AOD information, wherein remaining pixels on the display panel are deactivated during the AOD mode to reduce power consumption.

A circuitry for a touch and display panel, comprising:

• a touch sensing module configured to receive user touch input from the touch and display panel, wherein the user touch input corresponds to image data to be displayed on the touch and display panel;
• a display module comprising a first non-volatile memory array and a second non-volatile memory array, wherein:
• the first non-volatile memory array comprises a plurality of memory cells preprogrammed to store luminance correction data,
• the second non-volatile memory array comprises a plurality of memory cells configured to receive and store the image data to be displayed on the touch and display panel, and
• a logic circuit configured to generate digital data based on the luminance correction data and the image data;
• an input/output interface configured to convert the digital data into analog data and output the analog data to the touch and display panel for rendering.
