The present invention relates to a personal digital assistant (PDA) and an advertisement monitor (PDA) monitor based thereon, and more particularly, to replace a dot matrix LED display board currently used for text advertising, such as real estate and restaurants, video advertising Designed based on personal digital assistant (PDA) platform to support video, etc., individuals with embedded display interface circuits and related software to display promotional materials such as video and powerpoint on large display devices (PDP, LCD, OLED, etc.) The present invention relates to a mobile terminal (PDA) and an advertisement monitor (PDA) monitor device based thereon.

In general, as an advertising monitor device widely used in exhibition halls and stores, a general monitor or TV is used and a screen recorded with a DVD player is displayed, and a computer screen is connected to a computer instead of a DVD player. The most widely used method is a video display and a display board (usually 16 characters x 2 lines) that can be displayed using a dot matrix LED module and advertising by text or simple graphics. The product developed by combining large display devices such as PDP, LCD, and OLED based on personal digital assistant (PDA) platform to show and additionally change the contents of advertisement by having internet access function is not known yet. .

Recently, the latest video advertising device used in buses and subways is spreading by combining computer main board and LCD and installing Microsoft (MS) Windows operating system, but this is consumed by power consumption and hard disk (Windows capacity). This cursor hard disk is mandatory), because it requires reliability and stability, long initial boot time, and computer components built in as a standard, so it is limited in terms of price, so it is not generally used for advertisement (for outdoor use).

In order to solve this problem, when a large display device is combined with a personal digital assistant (PDA) platform, the weight is reduced by not using a separate hard disk, and the cost is greatly reduced, thereby ensuring reliability (temperature, humidity, shock) that can be used outdoors. The platform operating system can be provided at a price less than 10% (for example, WinCE, etc.) compared to Windows for computers, and does not require boot time due to the characteristics of the personal mobile terminal platform, and various peripheral devices (remote control, communication modem). Etc.) and can be widely used as an advertising device.

Recently, 42-inch PDP and LCD panels are falling below $ 800 due to the spread of large-sized digital TVs, and prices are expected to fall further. OLEDs are expected to be widely used. In order to advertise using such a display device, a DVD player or a computer must be used in connection with the display device. As shown in the present invention, when integrated with a display device through a display interface device, a video advertisement can be provided through a large screen. It is possible to change the advertisement contents with the memory card inserted through the expansion slot, but the advertisement contents can be remotely supported by supporting the mobile communication card, Bluetooth card, or wireless LAN card in the expansion slot (CF, PCMCIA, SD type, etc.). By changing the, it is possible to solve the difficulty of upgrading the advertising content which is a big problem of the existing advertising devices.

The advertisement contents can be composed not only with video playback but also with PowerPoint software, Internet, music, news, etc. in order to maximize the advertising effect by attracting customers' attention. On the other hand, the advertisement content itself can be placed on a central server and not on an advertisement monitor (PDA), so that the advertisement content can be provided by streaming through a wireless spot, Bluetooth, WiBro, or a mobile communication modem. You can access, monitor, edit, modify, change and delete the central server through the Internet.

On the other hand, the resolutions that can be supported in the personal mobile terminal platform are 640x480 for Microsoft's PocketPC, 1024x768 for WinCE, and 480x320 for Palm's Palm. Since the resolution of PDP and LCD panels is at least 852x480 up to 1920x1080 for HDTV, it is necessary to display the video generated through the personal mobile terminal platform using a large PDP and LCD panel. There is a problem that can not be supported without the present invention through.

The present invention has been proposed to solve the above problems, through the graphics processing hardware and programs to correct (change) the resolution of the PDA platform to match the resolution of the large display module to enable video advertising, etc. The purpose of the present invention is to provide a personal digital assistant (PDA) and an advertisement monitor (PDA) monitor based thereon.

That is, the present invention uses a large display panel instead of a small liquid crystal on a platform of a personal mobile terminal (CPU + audio + video + memory + various input / output interfaces) through a separate driving circuit (in the case of a PDP panel, an LVDS type output driving circuit). It can be connected and additionally equipped with wireless communication means such as wireless LAN, mobile phone module, Bluetooth module, etc., and software that integrates and operates, and resolution of PDA operating system which is lower than resolution of large display panel is large. It is an object of the present invention to provide a personal digital assistant (PDA) equipped with software or hardware for correcting the resolution of a display panel and a PDA device for advertising based thereon.

In addition, the present invention can be selected, changed, input, and used by operating a keyboard and a remote control through a large monitor screen as well as advertising, various functions of the personal digital assistant (PDA), a variety of voice and Unlike existing TV devices, text and data services can be directly connected to the network (in the case of existing interactive TV devices, text messages are connected to a mobile phone network through a wired telephone network), and various types of advertisements (videos) -> News-> Music-> Game-> Internet-> Messenger-> Advertisement Video) It is possible to provide a personal digital assistant (PDA) and a commercially available PDA monitor device based thereon. have.

In addition, the present invention, unlike the current advertising device, the future advertising device is not simply a one-way advertisement delivery as the present, but by the external operating device (for example, a remote control, a keyboard, etc.) or a touch screen input device, It should be able to evolve into an interactive form, such as providing the desired advertisement, information about things in the store, or providing web surfing, games, messengers, and free VoIP calls to keep consumers in front of the store. In order to reflect the demand that the advertising device is basically computerized, based on the personal digital assistant (PDA) platform that can provide a variety of interactive advertising means, such as a personal digital assistant (PDA) and the Another object is to provide an advertisement monitor (PDA) monitor.

Further objects and advantages of the present invention can be understood by the following description, and will be more clearly understood by the embodiments of the present invention. Also, it will be readily appreciated that the objects and advantages of the present invention may be realized by the means and combinations thereof indicated in the claims.

According to an aspect of the present invention, there is provided an advertisement monitor (PDA) monitor according to the present invention, comprising: a central processing unit for supporting a personal mobile terminal platform; A memory unit for storing various software and data; An audio signal processor for processing an audio signal; A graphic signal processor configured to generate an image displayed on a large display module in association with the central processor, and to interpolate a resolution of the maximum resolution of the operating system and the resolution of the large display module; User interfacing means for wirelessly providing a user interface; A driver for connecting the graphic signal processor and the large display module; An audio signal amplifier connected to the audio signal processor to drive a large speaker; And output means for outputting a personal mobile terminal operating system screen using the large speaker and the large display module.
