Abstract
The utility model relates to a twisted nematic liquid crystal display for a capacitance type touch switch, belonging to the field of liquid crystal displays. On the basis of a polarizer, ITO (Information Technology Outsourcing) glass, an ITO circuit, an oriented film and twisted nematic liquid crystal, pattern switching keys with a touch function are respectively arranged in the ITO circuit layer; and the public electrode and the pattern electrode of each switching key are connected with the control circuit of the liquid crystal. The twisted nematic liquid crystal display for a capacitance type touch switch has the advantages that the structure is simple because the touch switch and a display driving circuit are combined into a whole, volume is reduced, space is saved, cost is lowered, and the twisted nematic liquid crystal display is suitable for household electrical appliances.
Description
Technical field
The utility model relates to LCD, and specifically a kind of touch-control module and display apparatus module are integrated and have the LCD of touch switch function.
Background technology
LCD has advantages such as volume is little, in light weight, low-power consumption, therefore is used widely in all trades and professions.The used nematic LCD major part of household appliances is that CS is arranged in the package shell of display in the market; CS separates with LCD; Be not all one; Parts are more, so shortcomings such as such display has complex structure, volume is relatively large, weight is big, cost is high, consumptive material is many, use inconvenience.
Summary of the invention
The purpose of the utility model provides capacitance touching control switch nematic LCD, and it is integrated touch switch and display and replaces traditional silastic switch or thin film switch, and is simple in structure, and volume-diminished is practiced thrift cost, and is both artistic and practical.
In order to reach above purpose; The technical solution that the utility model adopts is to comprise Polarizer, ito glass, ITO circuit, oriented film and twisted nematic liquid crystals; It is characterized in that in the ITO line layer, being provided with the pattern switch key of tool touch controllable function, the public electrode of each switch key is connected with the control circuit of liquid crystal with pattern electrode.
In order to make the pattern switch key sense touch-control easily, the utility model will be arranged to the area greater than the pattern switch key in the end ITO line layer at the area of the pattern switch key in the face ITO line layer.
The pattern switch key of the utility model can be arranged on the left side of ITO line layer as required, or the right side, or upside; Or downside; Number has 2 to 16, can be regularly arranged in order according to the demonstration demand of reality, for example; Can show time, month, sky, concrete time from top to bottom respectively, confirm button such as key, other switch keys such as alarm clock can also be set.
During use, directly the touch pattern switch key is provided with or changes the content of display and gets final product.
Because the switch key that will be arranged on originally on the display group casing changes touch switch and integrated with display into, the utlity model has volume little, simple in structure, reduce cost and both artistic and practical advantage.
