Abstract:
The invention provides a computer module replacement design of a digital signage. The digital signage has a main circuit board and a plug-board disposed therein and connected to each other. The plug-board has a plug-card with a plug-slot, and a track disposed on each side thereof. The digital signage is covered up by a back cover so that an opening can be formed at one side edge of the digital signage. The computer module has a frame and a motherboard. The frame has a rail disposed on each side thereof and the motherboard has a slot and a connecting terminal disposed thereon. The slot has an interface socket card. The computer module can be placed into the digital signage through the opening with the rail placed into the track. Therefore, the connecting terminal is connected to the plug-slot and the computer module can be drawn out for maintenance.
Abstract:
A temperature conditioning system for outdoor digital signage and method thereof comprises a central control module, a system temperature sensor, a fan temperature sensor, a digital signage control module, an internal power supply module, a display module, a heating module and an external fan, wherein the central control module is responsible for receiving temperature signals detected by the system temperature sensor and the fan temperature sensor; in case the detected temperature is lower than a certain range, the central control module activates the heating module, the external fan and the display module in order to start and display the warm-up process of the outdoor digital signage. Consequently, when the temperature elevates to a certain range, the digital signage control module activates the power source of the outdoor digital signage such that the outdoor digital signage operates within a normal temperature range thereby preventing the dew formed by excessively low outdoor temperature from causing malfunction problems in the outdoor digital signage.
Abstract:
A heat dissipation system for digital electronic signboard includes a first heat dissipation subsystem disposed in a main circuit board area of a digital electronic signboard, and a second heat dissipation subsystem disposed in a computer mainboard area of the digital electronic signboard. The main circuit board area has a plurality of heat dissipation fans disposed therein, wherein one heat dissipation fan is disposed at a side of the main circuit board area, while another heat dissipation fan is disposed at a side of a power supply and can be externally connected to an air guide pipe. The computer mainboard area can also have a plurality of heat dissipation fans disposed therein, wherein one heat dissipation fan is disposed at a side of the computer mainboard, while another heat dissipation fan is disposed on the top of a microprocessor of the computer mainboard.
Abstract:
A supporting structure is applied to a backlight module including several optical sheets. The supporting structure includes a fixing component and a supporting component. The fixing component has a through-hole and an opening connected to each other. The supporting component includes a supporting pin, a block, a plate and a protrusion. The supporting pin has a top end for supporting the optical sheets and a bottom end at which the block is disposed. The plate is disposed on the supporting pin. The protrusion is disposed on the plate and faces the bottom end. After the block goes through the through-hole and rotates an angle, the plate and the block respectively press against upper and lower surfaces of the fixing component for clamping the fixing component. The protrusion is engaged in the opening for positioning the supporting component, so that the supporting component is fixed onto the fixing component.
Abstract:
A display device includes a display panel unit, a flexible cable, an electronic module, and a shield. The display panel has a side. The flexible cable is mounted on and extends along the side of the display panel unit, and is coupled electrically to the display panel unit. The electronic module is disposed on the side of the display panel unit, and is coupled electrically to display panel unit. The shield is disposed between the flexible cable and the electronic module. Accordingly, electromagnetic interference between the flexible cable and the electronic module can be prevented.
Abstract:
A support device includes a base member formed with an opening and a retention flange extending downwardly from the periphery defining the opening; a tubular sleeve extending upwardly from the base member and having a lower portion that is inserted into the opening in the base member and formed with a hook engaging the retention flange; and a holding post disposed within the tubular sleeve, and including an upper holding end exposed from the tubular sleeve and a lower enlarged end with a cross section greater than that of the upper holding end such that the lower enlarged end forcibly presses the lower portion of the tubular sleeve to abut against the retention flange of the base member in order to immobilize the holding post with respect to the tubular sleeve and consequently securing the tubular sleeve on the base member.
