The multimedia smart table of the present invention includes a touch screen display unit 100, an integrated control unit 200, an induction range 400, a sliding receptacle 500, a power supply unit for supplying power for driving the wireless power transmission unit 600 210 and a memory unit 220 for storing various programs and data necessary for system operation. The memory unit 35 may include a storage medium such as a random access memory (RAM), a read only memory (ROM), a hard disk (HDD), a compact disc (CD) It is preferable that the ROM is a ROM in which data is not erased even when the power supply is shut off.

The touchscreen display unit 100 includes a touch sensor 112 that supports a touch screen function. The touch sensor 112 may include a resistance film type, a capacitive type, an ultrasonic type, a tension measurement type, an infrared light type, Any one of the following methods can be used.

Here, the resistive film is formed by applying a resistance component on a glass plate and covering the film with a special film thereon. When a special current is applied to both ends of the resistive film in a shape in which a resistive component is applied to the inside of the special film and the insulating bar is raised at regular intervals so that the resistive component does not contact the glass surface, It is a method to detect touching part connected.

As shown in FIG. 4, the electrostatic capacitance type is formed by coating a transparent special conductive metal (TAO) material on both sides of the glass constituting the touch sensor, . A touch-sensitive touch screen uses glass coated with a thin metal conductive material. When a certain amount of current flows on the glass surface and a glass surface coated with a user's hand or an external object is touched, a certain amount of current is absorbed into the user's body , The touch screen recognizes the portion where the amount of current is changed and checks the touched portion.

In the ultrasonic method, when a transducer attached to a glass plate sends a surface wave, the opposite receiver receives the surface wave. Since the transmitted surface wave is constant, if a pressure is applied to a specific portion, the surface wave of the applied portion is weakened, and the x, y coordinates of the touch portion are read by the touch screen screen controller.

The tension measuring method is a method of detecting the coordinates of the touched point according to the degree of force applied to the touch screen monitor screen by attaching a sensor capable of measuring tension to the four corners of the touch screen monitor.

The infrared optical system utilizes the property that the infrared ray has a straight line and can not proceed because of obstruction. The pressure-sensitive part cuts off infrared rays coming from the horizontal and vertical directions, and reads the X and Y coordinates of the blocked part to detect it. That is, the infrared ray method is to confirm the touched position by intercepting the infrared ray of light on the front surface of the touch screen. The pressure method is to place a pressure sensor in a lattice pattern on the surface of the screen so that when the pressure of the user's hand or an external object is transmitted, the sensor senses the position of the place where the pressure is generated. When a pressure at a specific position is sensed, a function previously assigned to the position is automatically performed.

In a preferred embodiment, the touch screen display unit 100 may be a projected capacitive touch panel (P-CAP). The P-CAP touchscreen can detect multiple fingers at the same time as the projected capacitive touch panel has multiple sensors.

The 'project type' capacitive detection consists of implementing a detection matrix composed of conductive rows and columns arranged to detect local variations in capacitance introduced by the user's fingers or any other conductive input device. The 'projective capacitive' technique brings two main variants.

Self-capacitive " detection configured to read the rows of the matrix touch network and then read the columns; &Quot; Inter-capacitive " detection configured to read each intersection of the matrix-touch network. The 'mutual capacitive' technique requires reading the entire panel. Thus, if the matrix includes N rows and M columns, N x M acquisitions must be made, which is problematic in implementing large, high resolution panels at low number of responses. In addition, the measurement capability at 'mutual capacity' is weaker than that obtained at 'self capacity' detection, which is a problem when the user uses gloves.

The advantage of the 'self capacitive' detection is that for the previous panel, the system only needs N + M acquisitions to read the matrix. Figure 5 shows this principle. 1, the first finger presses the first intersection of column C I and row L J and the second finger presses column C K and row L L Press the second intersection. The output voltages (V OUT ) of the rows and columns indicate easily discernable level drops. The measured values of voltages for each level drop can be used to accurately identify the required rows and columns

Typical examples of the external device interface unit 700 include an RGB video input / output port for outputting RGB, a DVI video input / output port for outputting digital and analog simultaneously, a voice input / output port for outputting audio and video, a video input / output port, Various USB ports that can be connected to peripheral devices, a LAN port that can be connected to the Internet network, and a power port, but the number and type are not limited.
