Abstract

The present invention relates to a multi-function electronic board which can automatically switch between a writing function and a displaying function and can prevent screen blur. The multi-function electronic display having an integrated hardware structure including an embedded image processor, an embedded driving processor and software, comprises: an LCD panel unit which controls an electronic board S/W using an IR sensor and a multi-touch sensor of the LCD panel unit and includes a HOT KEY section for rapidly and easily executing and ending a S/W program and a control system by applying an IR cutoff type switch at the edge of the LCD panel unit; an IR sensor driver unit and a sensor driver unit which perform the commands outputted from the IR sensor and the multi-touch sensor as the internal units; an AD board for outputting images; a main power unit (SMPS) for supplying power to the LCD panel; a hard disk for storing data; a system panel including a PC power unit for supplying power to a main board and the hard disk; and a display unit including a computer driving unit composed of the main board having a CPU. Particularly, the present invention relates to a multi-function display for switching between a whiteboard function and a displaying function and preventing screen blur wherein the whiteboard function enables writing with a generic board marker, has a structure for supporting the board marker on the outside of the tray unit having a magnetic recognition reed switch sensor for automatically pausing an operation of the touch sensor on a display screen when using the board marker, controls the operation of the touch sensor by the tray unit which uses the magnetic recognition reed switch sensor according to board marker usage to prevent operational errors when the display is being used as the electronic screen or the white board, enables an automatic switching function between the electronic screen and the white board, enables a screen switching function between a touch type writing function and the displaying function, displays the same color as an exclusive writing pen on the screen by enabling a photo-coupler sensor provided in the tray unit to recognize an external color of the exclusive writing pen while a writing program is driven, forms a tunnel structure along the exterior of the LCD panel and a glass of the display unit, circulates the internal air of the LCD panel and the glass by producing an air current by operating a low-power fan provided at a lower portion of the tunnel structure, prevents screen blur by preventing the generation of fog and moisture within the glass, rapidly and easily executes and ends the S/W program and the system control using the HOT KEY section to apply the IR cutoff type switch at the edge of the screen, and enables screen control by applying the multi-touch sensor to the entire area of the screen.
