1. Field of the Invention
This invention relates to palm-type data processing devices, and, more particularly, to a touch screen palm-type data processing device.
2. Description of Related Art
Along with the rapid development of science technology and the electronics industry, palm-type data processing devices, such as personal digital assistants (PDAs), global positioning system (GPS) receivers and hand held computers, are more and more popular. Due to portability and an abundance of functions, palm-type data processing devices are becoming one of the most indispensable electronic products in the market.
Modern palm-type data processing devices are divided into three categories: candy-bar, clamshell and slide. A general candy-bar palm-type data processing device comprises a liquid crystal display in cooperation with a plurality of mechanical keys, both accessible on one rectangular face of the device. The mechanical keys may have different keyboard configurations, including numeric-type keyboards and QWERTY-type keyboards.
In order to satisfy various input function requirements, a palm-type data processing device is designed to have a specific keyboard configuration of mechanical keys. Accordingly, a palm-type data processing device has to further comprise a dedicated key set, housing mold, and application software executable by a key control chip that controls the mechanical keys, adding to the cost of such a palm-type data processing device.
A QWERTY keyboard may be in the form of a Chinese version (Hanyu Pinyin/Zhuyin Fuhao), Korean version, Japanese version, Germany version, Arabic version, English version, and so on, and, thus, may also have a variety of keyboard configurations. Two QWERTY keyboards of different language versions are not interchangeable. Therefore, the manufacturer often has to carry much stock for the various keyboard configurations of keyboards.
In view of the above-mentioned problems of the prior art, it is a primary objective of the present invention to provide a touch screen palm-type data processing device that does not need to employ physical keys of different display symbols requiring different design molds to accommodate different languages.
In order to achieve the above objective and other related objectives, the present invention provides a touch screen palm-type data processing device that includes: a microprocessor; a memory electrically connected to the microprocessor and stored with an operation program and a function program, the operation program, when executed by the microprocessor, displaying a keyboard configuration for a user to input data thereon, the function program, when executed by the microprocessor, providing a processing function; a function display unit electrically connected to the microprocessor and used for displaying a processing function picture after the microprocessor executes the function program; and a key touch control display unit electrically connected to the microprocessor and used for displaying a keyboard configuration after the microprocessor executes the operation program.
The following physical configurations exist: the function display unit and the key touch control display unit are contained in a single touch control display; the function display unit and the key touch control display unit are contained in two touch control displays, respectively; and, the function display unit is contained in a screen, and the key touch control display unit is contained in a touch control display.
The touch screen palm-type data processing device provides users with keyboard configurations of an input operation that the users desire to execute according to the operation program that are used for displaying the keyboard configurations, and may be designed with a housing mold of an identical specification with regard to various product models of different keyboard configurations, so as to achieve the objectives of reducing manufacturing and inventory costs.
The invention can be more fully understood by reading the following detailed description of the preferred embodiments, with reference made to the accompanying drawings, wherein:
The following illustrative embodiments are provided to illustrate the disclosure of the present invention and its advantages, these and other advantages and effects being readily understood by those in the art after reading the disclosure of this specification. The present invention can also be performed or applied by other embodiments. The details of the specification are based on specific features and applications, but numerous modifications and variations can be devised without departing from the spirit of the present invention.
The memory 11 is electrically connected to the microprocessor 12, and is stored with an operation program and a function program. The operation program, when executed by the microprocessor 12, displays a keyboard configuration for a user to input data thereon. The function program, when executed by the microprocessor 12, provides a processing function. The preset keyboard configuration is exemplified with a numeric type keyboard that is composed of ten numeric keys (0-9) and a plurality of function keys, as shown in
As embodied in
With the key touch control display unit 131, the touch screen palm-type data processing device may meet the requirements of clients for different keyboard configurations and provide required keys displaying content customized for a particular function to be manipulated by the user. Since the keyboard configuration of the device has a single specification only, the device is more easily manufactured, and solves the problem of requiring much stock for the accessories to be held in inventory.
In yet another embodiment, a touch screen palm-type data processing device of the present invention further comprises a selection unit (not shown), and the above-mentioned memory is stored with a plurality of operation programs that may, when executed, display different keyboard configurations, such that a user may manipulate the selection unit to select one of the keyboard configurations stored in the memory, and the touch screen palm-type data processing device is prompted to display the keyboard configuration selected by the user and provides an operation interface for the user. In an embodiment, the selection unit is a mechanical key that is electrically connected to the microprocessor and may be installed on a side of the housing 10, such that the user may easily manipulate the mechanical key. In another embodiment, the selection unit is a touch key that is displayed in the key touch control display unit. As exemplified in
With the selection unit that may be the physical keys on the device housing or virtual keys on the touch control display, the touch screen palm-type data processing device of the present invention may select a keyboard configuration that is needed for a particular usage, making the selection of the keyboard configuration more flexible.
In summary, the touch screen palm-type data processing device comprises an operation program that is stored in the memory for displaying a preset keyboard configuration. Thereby, the device can meet the requirements of a user for the keyboard configuration and display a required keyboard configuration. Thus, a device manufacturer, when facing the requirements of various customer groups for different keyboard configurations, may manufacture different keyboard configurations using an identical product specification, by the use of the device. Accordingly, the inventions addresses the problems of the prior art, wherein different corresponding molds have to be designed to address various keyboard configurations, various physical keys of different display symbols have to be bought to address different languages, the production efficiency is reduced, the accessories are not in common use, and the stock is hard to manage.
The foregoing descriptions of the detailed embodiments are illustrated to disclose the features and functions of the present invention and are not intended to be restrictive of the scope of the present invention. It should be understood by those in the art that many modifications and variations can be made according to the spirit and principles in the disclosure of the present invention and yet still fall within the scope of the appended claims.
