Abstract

An electronic book includes an electronic paper display module, an electrochromic unit, a light source module, and a light detecting unit. The electrochromic unit is arranged on the electronic paper display module and configured for adjusting a brightness for the electronic paper display module. The light source module is arranged on the electrochromic unit and configured for illuminating the electronic paper display module. The light source module includes a light guide member and a light source, the light source arranged at one side of the light guide member. The light detecting unit includes a light detector, a storage unit, and a control unit. The light detector is configured for detecting a brightness of ambient light, the storage unit is used for storing a preset value range, and the control unit is used for controlling the light source module and the electrochromic unit.

Description

technical field [0001] The invention relates to the display field, in particular to a front light module and an electronic paper display device including the front light module. Background technique [0002] In the prior art, the reflective electronic paper display device itself does not have a backlight module, and needs to reflect ambient light so that human eyes can see the picture displayed by the electronic paper display device. In the case of weak ambient light, due to the low brightness, the display effect of the electronic paper display device is not good, and it is difficult for the user to read. It is usually necessary to install a light source and a front light guide plate on the side of the light emitting surface of the electronic paper display device. The light emitted by the light source is guided by the front light guide plate into the electronic paper display device to reinforce weak ambient light, improve the display effect of the electronic paper display de...
