Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] see figure 2 As shown, it is a CPU-driven electronic ink screen of an EPD controller implemented by the present invention. As shown in the figure, the TV ink screen uses EPD to directly connect to the CPU, does not set an EPD controller, and uses an IO port to simulate an electronic ink screen. The control sequence of the ink screen drives the EPD of the electronic ink screen.

[0025] combine figure 2 with image 3 As shown, the EPD is directly connected to the CPU, and the specific connection relationship of each pin is as follows:

[0026] The PD0 pin of the CPU is connected to the ...

Abstract

The invention discloses an electronic paper display driven by a CPU without an EPD controller and a driving method. According to the electronic paper display, the EPD (Electronic Paper Display) is directly connected to the CPU, and an IO port is adopted to simulate a control sequence of the electronic paper display so as to drive the electronic paper display (EPD). According to the accomplished electronic paper display and the driving method, the common IO port is adopted to simulate the control sequence of the electronic paper display so as to drive the electronic paper display. The display of the electronic paper display is realized by the CPU or MCU without the EPD controller in the case of not additionally arranging the EPD controller according to the method.

Description

technical field [0001] The invention belongs to the technical field of electronic ink screens, in particular to a CPU-driven electronic ink screen of an EPD controller and a driving method. Background technique [0002] Electronic Ink Display (EPD for short) has the advantages of no flicker, no eye injury, power saving, etc., and has become the preferred display interface of e-readers. However, compared with traditional TFT, OLED and other displays, electronic ink screens have different control timing and more complicated drive control. Usually, it is necessary to add a dedicated EPD controller to drive the electronic ink screen; some manufacturers will integrate the EPD controller into the CPU. Among them, it becomes a CPU dedicated to electronic ink screens. The principle of these products is as follows figure 1 shown. [0003] For example, patent application 201310043731.X discloses an electronic ink screen, a method for switching display, and an electronic device. The...
