Abstract

A brightness control device is provided. The brightness control device includes an electric paper, a controller, a light sensor, and a memory device. The electric paper includes a plurality of pixels. The light sensor is used to sense intensity of surrounding light. The memory device is coupled to the controller and used to store control programs and light data. The controller is coupled to the electric paper and the light sensor. The controller is used to control the pixels of the electric paper to determine the transparency of the electric paper according to the intensity of surrounding light and manually control signals by employing an e-paper control method.

Description

technical field [0001] The present invention relates to a brightness control device, and in particular to a brightness control device using electronic paper. Background technique [0002] Generally, in order to prevent external light sources (such as sunlight) from being irradiated by glass windows in homes, curtains or blinds can be installed to block excessive external light sources. Or, general car windows will also be pasted with sunscreen paper to prevent excessive sunlight from outside. But curtains or blinds need to be manually operated. Sunscreen paper can't control the shading effect at will. [0003] Therefore, it is necessary to develop a brightness control device that can automatically or manually adjust the shading effect according to the intensity of the external light source. Contents of the invention [0004] The invention provides a brightness control device. The brightness control device includes an electronic paper, a light sensor, a memory and a con...
