Description

Monitor equipped with wireless data receiver {A MONITOR WHICH HAS WIRELESS RECEIVERS}

The present invention relates to a monitor equipped with a wireless receiver having an antenna, a frequency converter, a data processor, a memory, an interface, and a controller.

Personal computer is composed of CPU, memory, peripheral memory such as hard disk and floppy disk driver, modem, sound card, etc., and system unit called main unit, and peripheral device divided into output device and input device.

Peripherals that can be connected to the system unit include keyboards, mice, headphone microphones as input devices, and peripherals such as monitors, printers, and speakers as output devices. In addition, personal digital assistants (PDAs), mobile phones, digital cameras, electronic dictionaries, and the like are also increasingly connected to computers for input and output of data.

Most of the peripheral devices are wired and have a cord, a connector, a jack, and the like, and are connected to a system unit, but recently, a local area network using a wireless communication such as radio frequency or infrared communication (for example, a wireless local area network). As technology and short range personal area network technologies such as Bluetooth have evolved, various types of products using them have emerged.

As the use of various types of wireless peripherals such as wireless keyboards, wireless mice, digital cameras, personal digital assistants (PDAs), mobile phones, wireless microphones, etc. increases, wireless data from various types of wireless peripherals can be collected. Wireless data receivers for receiving are increasing, and more wireless peripherals are being used in the future.

Therefore, when all of these rapidly increasing wireless data receivers are used around a computer desk, there is a problem that the surrounding environment of the user's computer is complicated, and the inconvenience of reducing the use space of the computer desk is reduced. There is a problem that occurs.

As a method for solving the above problems, there is also a method of embedding the wireless data receiving apparatuses in the computer main body, but the operation angle of the wireless data receiving apparatus is generally 30˚ ~ 40˚ in that the computer main body is used under the desk. Limited to, it is not suitable to incorporate wireless data receivers into the computer body.

On the contrary, since a computer monitor generally needs to be placed on a desk and used by a user looking at the screen of the monitor, when the wireless data receiver is mounted on the computer monitor, the problem of the operation angle of the wireless data receiver as described above is not solved. Resolved.

The present invention has been made to recognize and solve the above problems, it is necessary to use a separate wireless receiver on the desk by providing an antenna, a frequency converter, a data processor, a memory, an interface and a control unit on the monitor It is an object of the present invention to provide a computer monitor equipped with a wireless receiver that provides a clean and concise user experience on a desk.

In order to achieve the above object, a conventional computer monitor including a display unit, an image signal processing unit, and a power supply unit, an antenna for receiving a radio signal having a radio frequency (RF) frequency from a wireless peripheral device, and received from the antenna A frequency converter for converting a frequency of a wireless signal into a baseband signal via an IF frequency (intermediate frequency), a data processor for processing wireless signals received from the frequency converter into computer data, and the wireless peripheral device And a memory unit for storing information on characteristics and functions of the computer and data for the computer, an interface unit electrically connected to an interface of the computer, and a controller for controlling the data processor, the memory unit, and the interface unit.

In addition, the interface unit is characterized in that any one of Universal Serial Bus (USB) and PCMCIA (Personal Computer Memory Card International Association) standards.

Hereinafter, a monitor equipped with a wireless receiver according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a monitor equipped with a wireless receiver according to the present invention.

The antenna receives a radio signal having a radio frequency (RF) frequency transmitted from a wireless peripheral device (not shown) such as a wireless keyboard, a wireless mouse, a digital camera, a PDA, a mobile phone, a wireless microphone, etc. and inputs it to a frequency converter. The frequency converter 20 includes a frequency converter, a power amplifier, and a low noise medium amplifier, and converts a radio signal having the radio frequency (RF) frequency into a baseband signal through an IF (intermediate frequency). . The structure of the frequency converter 20 has a structure used in the art.

The data processing unit 30 processes the baseband signal into a form that can be used by a computer (processed into a different form according to the bus standard of the interface used), and the memory unit 40 may be used as a wireless keyboard, a wireless mouse, or the like. It stores information on the characteristics and functions of wireless peripherals and stores data (computer data) in a form that can be used by the computer. The memory unit may use a RAM, and information on the characteristics and functions of the wireless peripheral device may be stored using a ROM (eg, an EEPROM).

The interface unit 60 transmits the computer data to the computer, and may use any one of a universal serial bus (USB) and a PCMCIA (Personal Computer Memory Card International Association) standard. However, it is not necessarily limited to the above standard, it is also possible to use other appropriate standards. The interface unit 60 is electrically connected to the interface 70 of the computer, and in the case of using the Universal Serial Bus (USB) standard, the interface unit is electrically connected to the USB port of the computer body through a cable. do.

The controller 50 may control the data processor, the memory, and the interface, and may use a microcontroller (MCU). The data processor 30 may also use an MCU.

The antenna 10, the frequency converter 20, the data processor 30, and the memory 40 may be configured in a single card and embedded in the monitor. It is also possible to configure by attaching at the position of.

2 is a view showing an example of a state in which the monitor according to the present invention is equipped with a wireless receiver.

The wireless data receiver 2 including the antenna 10, the frequency converter 20, the data processor 30, and the memory 40 is installed in a swivel 1 of the monitor. When the USB standard is adopted, a USB output port is installed at the rear of the swivel 1 to be electrically connected to the USB input port of the computer through a cable.

The wireless data receiver 2 is not necessarily installed in the swivel 1 of the monitor, but may be incorporated in the internal circuit of the monitor.

Instead of fixing the wireless data receiver 2 to a monitor, the wireless data receiver 2 can be configured to be detachable.

As described above, in the case of using the monitor equipped with the radio receiver according to the present invention, the following effects can be obtained.

First, since the computer work is performed while the user looks at the monitor screen, the wireless receiver is usually mounted on a computer monitor that is placed on a desk, and thus, when the wireless receiver is placed on a desk, the complexity of the desk is complicated. It is solved, and the computer environment is clean.

Second, in view of the fact that the operating angle of the wireless data receiving apparatus is generally limited to 30˚-40˚, when the wireless data receiving apparatus is installed in the computer main body and placed under the desk, the operation angle is out of the above operating angle. However, when the wireless data receiver is mounted on the monitor, the wireless peripheral device is generally used within the above angle with respect to the monitor, so there is an effect that the operation angle of the wireless data receiver does not need to be considered. .
