Definitions
- a large number of devices available today are equipped with display devices equipped with the help of a Input device, such as a keyboard, settings can be made and changed on the device.
- Examples of such devices are communication terminals, in particular mobile radio communication terminals. From physical For reasons these display devices are subject to aging processes, a readjustment of the supply voltage such display devices, especially in liquid crystal displays, make necessary.
- the invention sees a device with means for readjusting at least one operating parameter with features according to claim 1.
- the invention provides for readjustment by Limit value interval, the mean value of which is the current one Adjusts the value of the operating parameter. This will especially the readjustment of operating parameters is simplified, the changes due to aging or slow environmental influences subject. This is particularly advantageous if the readjustment is an operating parameter of a display device, for example the supply voltage of a colored LCD displays concerns because of this in practice a user is prevented from viewing the device made unusable by improper readjustment.
- the invention is based on a device that has means for readjustment of at least one operating parameter of this Device. These can be analog controls or input keys, with which depending on the duration or the Number of keystrokes changed the values of a parameter can be.
- the invention now provides that the readjustment one or more operating parameters is limited by a value interval that is defined by a Interval width and is defined by an average.
- the possible parameter values available for readjustment are within a range of values that extends around an average within an interval width. The smallest is therefore available for readjustment standing parameter value the mean value reduced by the half the interall width and the largest available for readjustment standing operating parameter value, the mean value is increased by half the interval width.
- the interval width can be in one dedicated storage device or as Software parameters.
- the invention provides the mean of an interval of values or the mean values of several value intervals in a storage device of the device so that it is possible is the stored mean values or the stored Overwrite mean value with current parameter values.
- the current parameter value as a new one Average of the value interval, i.e. as the new center of the value window is used.
- the invention therefore provides a device Means for readjusting at least one operating parameter before, with a value interval for readjustment of an operating parameter is available, the mean of which is in a Storage device of the device is stored, the stored value with the current value of the operating parameter can be overwritten, whereby after a new one Reading out the stored mean value whose new value is the Position of the value interval determined.
- a factory-set mean cannot be changed in the device, and the currently saved mean value can be adjusted with the factory set Mean value are overwritten so that after a new one Reading out the stored mean value of the factory-set Mean value determines the location of the value interval.
- Embodiment of the invention is particularly advantageous, according to which the effects of the readjustment of the supply voltage the display device during readjustment can be observed by the user because during the readjustment a test image is displayed on the display device becomes.
- a special embodiment of the Invention particularly advantageous if the display is colored, after which the test pattern during the readjustment of surfaces or objects with different colors shows their color values can be changed by the readjustment.
- a particularly advantageous operation of the device results then when stored mean values with current values when switched off Values of corresponding operating parameters overwritten so that when they are switched on again their values as new mean values are read out.
Description
Claims (6)
- Gerät mit Mitteln zur Nachregelung mindestens eines Betriebsparameters des Gerätes,
dadurch gekennzeichnet, daß
zur Nachregelung eines Betriebsparameters ein Werteintervall zur Verfügung steht, dessen Mittelwert (MW) in einer Speichereinrichtung (SE) des Gerätes abgespeichert ist, wobei der gespeicherte Wert mit dem momentanen Wert des Betriebsparameters (BPW) überschrieben werden kann, wodurch nach einem erneuten Auslesen des gespeicherten Mittelwertes dessen neuer Wert die Lage des Werteintervalls bestimmt. - Gerät nach Anspruch 1, bei dem zusätzlich ein werksseitig eingestellter Mittelwert (WEM) nicht änderbar gespeichert wird, und bei dem der momentan gespeicherte Mittelwert (MW) mit dem werksseitig eingestellten Mittelwert (WEM) überschrieben werden kann, so daß nach einem erneuten Auslesen des gespeicherten Mittelwertes der werksseitig eingestellte Mittelwert die Lage des Werteintervalls bestimmt.
- Gerät nach einem der vorhergehenden Ansprüche, bei dem die Versorgungsspannung (VS) einer Anzeigeeinrichtung (AE) des Gerätes ein derartiger nachzuregelnder Betriebsparameter ist.
- Gerät nach Anspruch 3, bei dem die Auswirkungen der Nachregelung der Versorgungsspannung der Anzeigeeinrichtung während der Nachregelung vom Benutzer beobachtet werden können, weil während der Nachregelung ein Testbild (TB) auf der Anzeigeeinrichtung angezeigt wird.
- Gerät nach Anspruch 4 mit einer farbigen Anzeige, bei der das Testbild während der Nachregelung Flächen oder Objekte mit unterschiedlichen Farben zeigt, deren Farbwerte durch die Nachregelung verändert werden.
- Gerät nach einem der vorhergehenden Ansprüche, bei dem beim Ausschalten gespeicherte Mittelwerte mit momentanen Werten entsprechender Betriebsparameter überschrieben werden, sodaß bei erneutem Einschalten deren Werte als neue Mittelwerte ausgelesen werden.
