Description

Mobile display device supporting split screen function {Mobile display apparatus supporting PBP}

The present invention relates to a mobile display device, and more particularly, to a mobile display device supporting a split screen display function.

In recent years, with the transition to the information age, the demand for simpler, more convenient and faster information acquisition and information exchange is increasing. Thanks to the development of computer manufacturing technology, wireless communication technology, and microchip manufacturing process, mobile electronic products that meet these requirements are being developed and released. Representative mobile electronic products include laptop PC, Examples include web pads, personal digital assistants (PDAs), and smart display devices.

In the case of such a portable electronic device, the portable electronic device must have a volume and weight that can be carried, and thus, there are limitations in comparison with the manufacture and development of existing electronic equipment. In general, a docking station is utilized to enable more efficient use of such portable electronic devices.

A docking station refers to a set of interfaces and hardware equipment that services portable electronics more effectively. That is, communication with a local printer, mass storage device or backup drive, and other possible devices, which are not attached to the portable electronic device, makes it possible to utilize the portable electronic device more efficiently. The docking station may also include a network interface card such that the portable electronic device can be connected to a local area network (LAN). Recently developed and commercially available wireless Internet services of notebook PCs can be implemented by using such a docking station.

On the other hand, in addition to notebook PCs, which have been recognized as typical portable electronic devices, smart display devices have recently been paying attention as next-generation mobile devices that will open the era of one-to-one PCs. A smart display device is a kind of portable monitor that has a form similar to a laptop or PDA. It is connected to a host PC serving as a server in an enterprise or home by using a wireless LAN method to attract computing resources. It works in writing. In order to use a smart display device, a prerequisite that a server-based computing (SBC) wireless infrastructure must be created in a home or an enterprise.

1 illustrates a general configuration of a smart display device that is recently attracting attention as a mobile device device.

According to the drawing, the smart display device 10 is docked and used in a situation where the host PC 30 and the docking station 20 are equipped. When the smart display device 10 is undock from the docking station 20, the smart display device 10 acts as a kind of wireless monitor mode by wirelessly connecting the host PC 30 with the wireless module and is docked. In a situation it will act as a regular monitor.

In FIG. 2, a process of processing an input signal in the conventional smart display device 100 is represented by a simple block diagram.

According to the drawing, the smart display device 100 has a structure that can be used in connection with the docking station 200 through the docking unit 150. When docking is performed, the wired input signal is received through the docking unit 150 and input to the scaler 130. The scaler 130 generally serves to adjust the scale and / or resolution of the input signal to suit the product specifications of the smart display device 100.

On the other hand, the wireless module 140 is a device that receives a wireless input signal transmitted to the radio frequency from the outside and outputs directly to the image signal processor 120 without passing through the scaler 130. When the image signal processing unit 120 determines whether the control unit (not shown) docks and sends a control signal, the image signal processing unit 120 selectively uses a wire / wireless input signal input through the scaler 130 and the wireless module 140 using its own switch. It is converted into a signal that can be received and output.

The output unit 110 displays a signal converted by the image signal processor 120 on the screen. In a mobile product such as the smart display device 100, a smaller and lighter LCD monitor may be used as the output unit 110.

4A and 4B show screens represented by the PBP method and the PIP method, respectively. As shown in the figure, the PBP method divides the screen into two and outputs different images (images 1 and 2), and the PIP method (or caption method) refers to a small sub-screen (image 2) on a part of the main screen (image 1). Is the way to show.

The screen output of the PBP method and the PIP method is basically required to properly adjust the size of the image 1 and the image 2, and this action is a role of the scaler 130. The scaler 130 adjusts the output scale of signals input through two different channels in half (PBP method) or adjusts the output scale of one input signal to the scale of the sub screen (PIP method). Makes it possible.

According to the related art, since the signal input through the wireless module 140 is directly input to the image signal processing unit 120 without passing through the scaler 130, there is a problem that the split output is impossible.

The present invention has been made to solve the above problems, an object of the present invention is to provide a mobile display device capable of split screen output by scaling the wireless input signal input through the wireless module using a scaler. .
