Abstract
The utility model discloses a dynamic visual organic light emitting diode (OLED) keyboard. The technical scheme is that: the dynamic visual OLED keyboard comprises keys and a keyboard body, wherein each key is an OLED display key with a liquid crystal display screen; and an adjustment knob for adjusting the brightness of the liquid crystal display screens is arranged on the keyboard body. The dynamic visual OLED keyboard has the beneficial effects that: a serial port communicates with an upper computer, so that peripherals can be controlled; functions of the keys are simple, intuitive and clear at a glance; patterns displayed by the keys can be changed dynamically, and contents displayed by the keys can be changed as required; and the brightness of the keys can be adjusted, so that different requirements on environment brightness are met.
Description
Technical field
The utility model relates to the adjustable brightness OLED keyboard of a kind of dynamic and visual OLED keyboard, the especially dynamic of button displaying contents and function configurability.
Background technology
Keyboard is the human-computer interaction device who uses always, is widely used in various controls field.The keyboard that uses in the market is conventional keyboard mostly, and keypress function is not directly perceived, keypress function memory difficulty more for a long time especially, maloperation easily; Existing OLED keyboard, it mainly is to research and develop to playing, though relatively more directly perceived,, can be self-defined few from the number of keys of programming, can not carry out brightness regulation.Along with OLED presses the increasingly mature of key technology, the application of OLED keyboard in engineering project also becomes industrial trend.
Summary of the invention
Deficiency to stiff directly perceived, the aspect such as function is fixed, can't be expanded of traditional keyboard; The invention provides the technical scheme that a kind of OLED shows supervisory keyboard, adopt this technical scheme to communicate by letter with host computer, realize control peripherals through serial ports; The keypress function simple, intuitive; Come into plain view, the pattern that button shows can dynamic change, and changes the button displaying contents as required; Button brightness can be regulated, and satisfies the varying environment brightness requirement.
The utility model is realized through following technical measures: a kind of dynamic and visual OLED keyboard; It comprises button and keyboard body; Each button is the OLED display button that has LCDs, and said keyboard body is provided with the adjusting knob that is used for the brightness of regulator solution crystal display screen.
The concrete characteristics of the utility model also have; Above-mentioned button is electrically connected with keyboard scanning circuit, serial communication circuit; Said keyboard scanning circuit, serial communication circuit are electrically connected with microprocessor; Said microprocessor is electrically connected with the A/D signal processing circuit, and said A/D signal processing circuit is electrically connected with said adjusting knob, and said microprocessor can be electrically connected with host computer through serial communication circuit.
The beneficial effect of the utility model is: this keyboard control system possesses keyboard scanning circuit, and whether can monitor in real time has key to press.Keyboard scanning circuit is judged the level state of ranks through the rank scanning mode, confirms the position at the current place that pushes button.
Microprocessor can through serial communication circuit, carry out typing to button storage inside content and upgrade according to the host computer information that obtains.
Analog-digital chip can convert the analog feedback signal from the brightness regulation knob into digital signal, offers microprocessor then, and microprocessor is judged the brightness degree that current keyboard should reach according to data measured.When operating personnel regulated the keypad brightness knob, microprocessor can be judged the current knob data message that receives, and through button is write configuration information, thereby regulated button brightness.Can satisfy under the varying environment illumination condition different demands to keypad brightness.
This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
