Abstract: The present disclosure discloses a method for processing a report point data, a handwriting reading device and a computer storage medium. The method for processing the report point data includes: transmitting report point data associated with received handwriting to a display controller by a System on Chip; looking up a LUT table and acquiring a first waveform of driving an ink screen based on the report point data by the display controller; and driving the ink screen to display the handwriting using the first waveform by the display controller.

Abstract: The disclosure relates to an ink screen reading device, a screen driving method thereof and a storage medium. The method comprises: acquiring a current temperature value of a screen; judging whether the current temperature value is lower than a preset first temperature value; in condition that the current temperature value is lower than the first temperature value, choosing a second temperature value and looking up a preset table according to the second temperature value and grayscale values of content to be displayed to obtain a waveform of the screen; in condition that the current temperature value is higher than or equal to the first temperature value, looking up the table according to the current temperature value and the grayscale values of content to be displayed to obtain the waveform of the screen; and driving the screen by the waveform to display the content to be displayed.

Abstract: The disclosure provides an accessory apparatus for an electronic device having a page-turning function, an electronic device and an electronic device assembly. The accessory apparatus comprises: a protective cover, which partially or completely wraps the electronic device and directly attaches to a back of the electronic device, wherein the protective cover is connected to an outer surface of the electronic device; a page-turning button, which is configured to perform a page-turning operation; a flexible printed circuit, which is provided with a page-turning triggering component, wherein the page-turning triggering component is in contact with the page-turning button and is configured to detect a page-turning instruction in response to the page-turning operation, and wherein the page-turning instruction is transmitted to the electronic device by the flexible printed circuit and a support member, which is configured to support the flexible printed circuit.
