Abstract

The invention discloses an electronic paper reader capable of providing illumination, and belongs to the field of digital reading. The reader comprises a main controller unit for running a system program, an electronic paper display unit for displaying content, a drive circuit unit for driving the electronic paper display unit to work, a lighting unit embedded into the electronic paper reader, and a brightness control unit for adjusting illumination intensity of the lighting unit, wherein, the lighting unit consists of a light-emitting diode (LED) and a light equalizer, and the LED is fixed on the light equalizer. The electronic paper reader has the advantages that the problem that the electronic paper reader can not be used in a darker environment owing to failure in active luminescence is effectively overcome; illumination can be provided to a display screen by switching on the lighting unit under an insufficient external light or dark condition; and light intensity can be adjusted according to the demand of a user.

Description

technical field [0001] The invention belongs to the field of digital reading, and relates to an electronic paper reading device, in particular to an electronic paper reader capable of providing illumination. Background technique [0002] As a tool for browsing e-books, the electronic paper reader uses electronic paper with a paper-like display function on its display screen, which can bring users the feeling of reading paper books. The electronic paper reader does not consume power in the display state, but only consumes power when the screen is refreshed. Therefore, the electronic paper reader not only helps protect eyesight, but also has low power consumption, which is extremely power-saving, energy-saving and environmentally friendly. However, the screen of an e-paper reader is different from an LCD screen. It has no backlight and cannot actively emit light. In a dark or completely dark environment, the screen content cannot be displayed. The reading function of the e-pa...
