Patent ID: 11862116
Assignee: SHENZHEN ZHANGYUE TECHNOLOGY CO., LTD
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 12:
13. A non-transitory computer readable storage medium storing executable instructions, wherein the executable instructions upon execution by a processor cause the processor to perform operations of:
transmitting report point data associated with received handwriting to a display controller directly from a hardware layer of a System on Chip;
looking up a LUT table (Look-Up-Table) and acquiring a first waveform of driving an ink screen based on the report point data by the display controller, wherein the looking up the LUT table and acquiring the first waveform of driving the ink screen based on the report point data by the display controller further comprises:
receiving the report point data by the display controller,
establishing a layer cache by the display controller,
generating the first image of the handwriting in the layer cache based on the report point data by the display controller, and

looking up the LUT table and acquiring the first waveform of driving the ink screen based on the first image of the handwriting by the display controller;
driving the ink screen to display a first image of the handwriting using the first waveform by the display screen controller; and
wherein the operations further comprise:
transmitting the report point data associated with the received handwriting to an application layer of the System on Chip by a core layer of the System on Chip;
generating a second image of the handwriting based on the report point data by the application layer;
converting the second image into a grayscale image by the application layer;
transmitting the grayscale image to the core layer by the application layer;
transmitting the grayscale image to the display controller by the core layer;
looking up the LUT table and acquiring a second waveform of driving the ink screen based on the grayscale image by the display controller; and
driving the ink screen to display the second image of the handwriting using the second waveform by the display controller.
