GEBIET DER ERFINDUNGFIELD OF THE INVENTION
Die vorliegende Erfindung betrifft eine Flüssigkristallanzeige, welche mit einer Berührungsvorrichtung zusammengefasst ist, wobei diese genauer eine Flüssigkristallanzeige betrifft, welche mit einer kapazitiven Berührungsvorrichtung zusammengefasst ist.The The present invention relates to a liquid crystal display which with a touch device is summarized, which relates more specifically to a liquid crystal display, which with a capacitive touch device is summarized.
HINTERGRUND DER ERFINDUNGBACKGROUND OF THE INVENTION
Flüssigkristallanzeigen
(LCDs) mit verschiedenen Gestaltungen werden von der Bevölkerung
allgemein verwendet. Bezüglich
Das
Flüssigkristallanzeigemodul
Durch die Industrie wurden bestimmte Techniken zur Zusammenfassung einer Flüssigkristallanzeigetafel und einer Berührungsvorrichtung entwickelt, welche die Bedienung vereinfachen kann. In einem frühen Stadium umfasste die Berührungsvorrichtung Widerstandsfilme. Wenn ein Gegenstand die Oberfläche der Berührungsvorrichtung berührt, bewirkt eine Belastung, welche durch den Gegenstand erzeugt wird, dass sich die zwei Widerstandsfilme gegenseitig berühren, so dass ein Schalter eingeschaltet wird und ein Berührungssignal zur Verarbeitung zum Bestimmen der Berührungsposition zu einer Steuereinheit gesandt wird. Bei langfristiger Verwendung werden die Widerstandsfilme jedoch infolge häufigen Drückens beschädigt, und es wird schwierig, die Berührungsposition genau zu bestimmen.By The industry has been used to summarize certain techniques Liquid crystal display panel and a touch device developed, which can simplify the operation. At an early stage included the touch device Resistance films. When an object touches the surface of the touch device causes a stress generated by the object that is the two resistive films touch each other, leaving a switch is turned on and a touch signal for processing to determine the touch position to a control unit is sent. For long-term use, the resistance films become however, as a result of frequent pressing damaged, and it gets difficult, the touch position to be determined exactly.
Um die Mängel der Gestaltungen unter Verwendung von Widerstandsfilmen, welche oben erwähnt wurden, zu überwinden, wurde eine kapazitive Berührungsvorrichtung entwickelt. Eine kapazitive Berührungsvorrichtung umfasst zwei berührungsempfindliche Schichten und eine mittlere Schicht, welche zwischen den zwei berührungsempfindlichen Schichten angeordnet ist. Bei dem Herstellungsvorgang werden die Flüssigkristallanzeigetafel und die kapazitive Berührungsvorrichtung getrennt hergestellt, und sodann werden diese gestapelt angeordnet und aneinander befestigt. Ein Verwender kann einen leitfähigen Gegenstand, wie etwa einen Finger oder einen Stift, verwenden, um die Kennsymbole auszuwählen, welche auf der Oberfläche der Berührungsvorrichtung dargestellt sind, um Bedienungsvorgänge auszuführen bzw. Daten einzugeben.Around the deficiencies the designs using resistance films, which mentioned above were to overcome became a capacitive touch device developed. A capacitive touch device includes two touch-sensitive Layers and a middle layer, which between the two touch-sensitive layers is arranged. In the manufacturing process, the liquid crystal display panel becomes and the capacitive touch device made separately, and then they are stacked arranged and attached to each other. A user may choose a conductive object such as a finger or a stylus, to select the identification symbols which on the surface the touch device are shown to perform operations or enter data.
ZUSAMMENFASSUNG DER ERFINDUNGSUMMARY OF THE INVENTION
Es ist jedoch erforderlich, eine Schutzschicht getrennt an der Oberfläche der Berührungsvorrichtung und denen der Flüssigkristallanzeigetafeln anzubringen. Die Schutzschichten werden hauptsächlich aus Glas hergestellt. infolgedessen erfordert die Verwendung von zwei Schutzschichten den Verbrauch einer großen Materialmenge bei der Herstellung. Ferner werden Berührungsvorrichtungen und Flüssigkristallanzeigen getrennt hergestellt, und sodann werden diese gestapelt angeordnet und aneinander befestigt. Ein derartiger Montagevorgang ist kompliziert und zeitaufwändig und tendiert ferner zur Produktion mangelhafter Produkte. Ferner weisen die Produkte, welche in dieser Weise hergestellt werden, eine größere Dicke auf, und es ist schwierig, die gesamte Vorrichtung zu verschlanken.It However, it is necessary to have a protective layer separately on the surface of the touch device and those of the liquid crystal display panels to install. The protective layers are mainly made of glass. As a result, the use of two protective layers is required the consumption of a big one Quantity of material during production. Further, touch devices become and liquid crystal displays made separately, and then they are stacked arranged and attached to each other. Such an assembly process is complicated and time consuming and also tends to produce defective products. Further have the products that are produced in this way, a greater thickness and it is difficult to slim down the entire device.
Es ist eine Aufgabe, eine Flüssigkristallanzeige mit einer integrierten kapazitiven Berührungsvorrichtung zu schaffen, welche keine zusätzlichen Basisplatten erfordert. Dadurch kann erreicht werden, dass die Vorrichtung schlank ist.It is a task, a liquid crystal display to provide with an integrated capacitive touch device which no additional base plates requires. This can be achieved that the device is slim is.
Die Flüssigkristallanzeige der vorliegenden Erfindung umfasst eine Flüssigkristallanzeigetafel, eine erste Elektrodenschicht und eine zweite Elektrodenschicht. Die Flüssigkristallanzeigetafel umfasst ein Flüssigkristallanzeigemodul, welches eine obere Polarisationsscheibe und eine untere Polarisationsscheibe umfasst. Die erste Elektrodenschicht umfasst eine vorbestimmte Elektrodenstruktur, welche an der Oberseite der oberen Polarisationsscheibe ausgebildet ist. Die zweite Elektrodenschicht umfasst eine vorbestimmte Elektrodenstruktur, welche an der Unterseite der unteren Polarisationsscheibe ausgebildet ist.The liquid-crystal display The present invention comprises a liquid crystal display panel, a first electrode layer and a second electrode layer. The liquid crystal display panel comprises a liquid crystal display module, which is an upper polarizing disk and a lower polarizing disk includes. The first electrode layer comprises a predetermined electrode structure, which is formed on the upper side of the upper polarizing disk is. The second electrode layer comprises a predetermined electrode structure, which is formed on the underside of the lower polarizing disc is.
Gemäß einem weiteren Ausführungsbeispiel sind lediglich eine Flüssigkristallanzeige und eine kapazitive berührungsempfindliche Schicht aufgenommen, wobei die kapazitive berührungsempfindliche Schicht an der Oberseite bzw. an der Unterseite der oberen Polarisationsscheibe ausgebildet ist.According to one another embodiment only a liquid crystal display and a capacitive touch-sensitive Layer, wherein the capacitive touch-sensitive layer at the top or at the bottom of the upper polarizing disk is trained.
Mittels der vorliegenden Erfindung kann eine Zusammenfassung der Flüssigkristallanzeige mit einer kapazitiven Berührungsvorrichtung erreicht werden, ohne gesonderte Basisplatten zu verwenden. Dies trägt nicht nur dazu bei, zu erreichen, dass die gesamte Vorrichtung die Anforderungen der Produkte eines schlanken Typs erfüllt, sondern auch dass ihr Gewicht reduziert wird. Genauer wird die Flüssigkristallanzeige in einem einfachen Herstellungsvorgang direkt mit einer kapazitiven Berührungsvorrichtung zusammengefasst, anstatt nach getrennten Herstellungsvorgängen zusammengesetzt zu wer den. Dies ist mit vielen Vorteilen verbunden, wie etwa einem einfachen Herstellungsvorgang, hoher Produktionsausbeute und niedrigen Herstellungskosten. Ferner kann die Elektrodenschicht aufgrund der Tatsache, dass die Elektrodenschicht an der Oberseite der oberen Polarisationsscheibe der Flüssigkristallanzeige angebracht ist und sich näher bei dem Finger bzw. einem anderen Berührungsgegenstand befindet, somit eine Berührung empfindlicher erfassen.By means of the present invention, a summary of the liquid crystal display with a capacitive touch device can be achieved without using separate base plates. Not only does this help to ensure that the entire device meets the requirements of the products of a slim type, but also that their weight is reduced. More precisely, the liquid kris tallanzeige summarized in a simple manufacturing process directly with a capacitive touch device, rather than assembled after separate manufacturing operations to who. This is associated with many advantages, such as a simple manufacturing process, high production yield and low production costs. Further, due to the fact that the electrode layer is attached to the upper surface of the upper polarizing disk of the liquid crystal display and is closer to the finger or other touch object, the electrode layer can more sensitively detect a touch.
