Abstract: An electronic system comprises a mobile apparatus and a reading apparatus. The reading apparatus has a display screen and a plurality of operation units. When the reading apparatus is linked with the mobile apparatus through a data-transmission interface, the reading apparatus displays an image of an electronic file on the display screen thereof which is stored in the mobile apparatus. When one of the operation units is enabled, the reading apparatus generates a corresponding operation signal to the mobile apparatus, thus the mobile apparatus performs a corresponding operation process according to the operation signal.

Abstract: A writing method for E-paper includes the following steps. A writing device for E-paper is provided, which includes a first writing electrode and a second writing electrode facing to the first writing electrode. A writing space is defined between the first writing electrode and the second writing electrode. Next, an E-paper is disposed into the writing space. Next, a voltage is applied on the first writing electrode and/or the second writing electrode to generate an electric field in the writing space. Next, the first writing electrode and the second writing electrode are driven to move with respective to the E-paper so that the E-paper is written by the electric field in the writing space. The E-paper can be written without a writing circuit configured therein by the writing method, thereby the production cost of the E-paper can be reduced and the E-paper is facilitated to carry. Furthermore, A writing device for E-paper is also provided.

Abstract: A method for assembling a liquid crystal display device includes: a) assembling together a front frame, a liquid crystal panel and an optical plate unit in a dust-free environment to form a first unit in a manner that the liquid crystal panel closes an opening in the front frame and that a sealed state is established between the liquid crystal panel and the optical plate unit; b) assembling a circuit board to one side of a rear frame without requirement of a dust-free environment to form a second unit; c) assembling a light source to one of the first and second units; and d) interconnecting the first and second units without requirement of a dust-free environment in a manner that the light source is able to provide light to a light-entrance surface of the optical plate unit.

Abstract: A backlight module includes a first light source, a back plate unit, a reflector unit, and a light guide plate. The back plate unit includes a first back plate and a second back plate. The first back plate has a first plate body with a first side part structure defining a first receiving space for receiving the first light source, and the second back plate has a second plate body with a second side part structure. The second back plate is connected to the first back plate in a manner that the first and second side part structures are opposite to each other. The reflector unit is disposed on the first and second plate bodies, and has a portion extending into the first receiving space. The light guide plate is disposed on the reflector unit and is disposed between the first and second side part structures.
