Abstract
This disclosure provides an electronic paper device which includes an electronic paper display, an application circuit, and a microprocessor. The microprocessor establishes a communication connection with an external device to continuously receive image data, and stores the image data in a buffer memory of the microprocessor. This image data is a portion of a frame. When the communication connection enters an idle state, the microprocessor writes the image data into the electronic paper display through the application circuit without initiating a refresh process of the electronic paper display.
Claims15
An electric paper device, comprising:
- an electric paper display;
- an application circuit, electrically connected to the electric paper display;
- and
- a microprocessor having a buffer memory and being electrically connected to the application circuit, wherein the microprocessor is configured to establish a communication connection with an external device for continuously receive image data and store the image data into the buffer memory, wherein the image data belongs to a portion of a frame,
- wherein when the communication connection enters an idle state, the microprocessor is configured to write the image data into the electric paper display through the application circuit without initiating a refresh process of the electric paper display.
A controlling method for an electric paper device, the electric paper device comprises an electric paper display, an application circuit, and a microprocessor, the controlling method comprising:
- establishing, by the microprocessor, a communication connection with an external device for continuously receive image data, wherein the image data belongs to a portion of a frame;
- storing the image data into a buffer memory of the microprocessor;
- and
- when the communication connection enters an idle state, writing, by the microprocessor, the image data into the electric paper display through the application circuit without initiating a refresh process of the electric paper display.
A non-transitory computer readable storage medium storing a plurality of instructions which are configured to perform a plurality of steps:
- establishing, by a microprocessor, a communication connection with an external device for continuously receive image data;
- storing the image data into a buffer memory of the microprocessor, wherein the image data belongs to a portion of a frame;
- and
- when the communication connection enters an idle state, writing, by the microprocessor, the image data into an electric paper display through an application circuit without initiating a refresh process of the electric paper display.
