Abstract: A hidden image capturing device is applied to a display. The hidden image capturing device has a shell, a control module, a slide module, and an image capturing module. The slide module is disposed in the shell and controlled by the control module for sliding. Besides, the slide module enables the image capturing module to extend out or withdraw into the shell when it slides.

Abstract: A handheld electronic device including a body and an image capturing module. A display is disposed on one surface of the body. The image capturing module is disposed at the body, and includes a lens and a filter unit. The lens is exposed from an opening on the body. Images captured by the lens are displayed on the display. The filter unit includes at least one first filter, one second filter, and a switch. Each of the first filter and the second filter transmits light with different wavelength. The switch is used to switch the first filter and the second filter so that one of the first filter and the second filter is on the light receiving path of the lens.

Abstract: A multimedia system is provided. The multimedia system relates to a main frame and at least a portable display device to proceed with transmission and communication. The portable display device includes a display module to display multimedia digital data, an image decoding module to receive and send a multimedia digital data, and a peripheral control module to select and control multimedia digital data. The wireless module is through many-to-one wireless two-way transmission to receive and send digital signals delivered by the wireless module of the main frame. The main frame not only has general computer's functions but also has multifunctional uses of digital TV playing, web surfing, disk playing, wireless transmission and so on. The portable display device has characteristics of light weight and easy to carry. Through the main frame to proceed with wireless transmission, it will not be limited by wiring distance.

Abstract: A liquid crystal display (LCD) capable of negative ion generation is disclosed. The LCD utilizes existing power inverter to generate negative ions by means of corona discharge or silent discharge, which offers an extra function without altering the structural design of existing power inverter while saving the space required for generation of negative ions. In addition, the LCD excites negative ions with little power without affecting its normal operation. Using the LCD disclosed in this invention not only neutralizes the adverse effect of positive ions on human body, the negative ions produced by the display can help purify blood, activate cells, boost immunity, regulate autonomous nerves and remove harmful substances, suspended particles, and odors in air, and kill germs. It benefits the health of people who use computer constantly.

Abstract: A notebook computer with hidden multimedia controller. The notebook computer has a cavity and a multimedia device. A multimedia controller with a plurality of keys to control the multimedia device movably pivoted to the main body. The notebook computer has a switch with a rod. Two magnets are individually disposed on the rod and the multimedia controller. The multimedia controller is attracted, remaining in the cavity. When the switch is pressed, the multimedia controller is pushed out from the cavity by the repulsive magnetic force.
