The color filter layer is arranged on the lower surface of the first substrate and comprises a plurality of pixels and a plurality of color resistors, and the color resistors are respectively arranged between adjacent two pixels. The lower surfaces of the second substrate and the first substrate are arranged correspondingly. The liquid crystal layer is clamped between the first substrate and the second substrate. The plurality of first sensors are located on the upper surface of the first substrate and can send out signals by sensing the changes of the resistors; and the first sensors are arranged at interval; the plurality of second sensors are located on the upper surface of the second substrate and can sense an infrared light to send out signals, and the second sensors correspond to the color resistors. The first polarizing plate is arranged on the plurality of first sensors. The second polarizing plate is arranged on the lower surface of the second substrate. And the back light module is arranged below the second polarizing plate. With the touch screen provided by the invention, the touch way can be selected as required.
Description
Technical field
The present invention relates to a kind of touch control display, relate in particular to a kind of touch control display that can between dual mode, change.
Background technology
In the past, computer is institute's role in people's life, was to be responsible for data run and word processing.Along with developing rapidly of electronics industry with progressive; Computer not only significantly promotes on performance; For example increase network communication, accelerate the speed of data operation processing etc., also make rapid progress in appearance, volume is especially towards light, thin, short, little direction evolution; So traditional computer has had desktop computer to develop into portable computer (like mobile phone, palmtop computer, individualized digital assistants etc.); To save usage space effectively, meet the trend of Modern Electronic product, and its input media also changes contact panel (touch panel) into by traditional keyboard or mouse etc.
The touch type of existing contact panel is divided into that resistance-type, condenser type or infrared induction etc. are hand-written controls the induction touch control manner and pen is write and controlled the induction touch control manner.Yet,, it used and operate comparatively inconvenience because at present the display device of touch control manner only provides single touch-control interface mode mostly.In addition, though because the hand-written induction touch control manner of controlling can provide multi-point touch, overdue easily or operation identification is difficult for; And pen is write and is controlled the induction touch control manner, comparatively accurately stablizes on identification and touch-control with respect to the hand-written induction touch control manner of controlling, but function of multi-spot touch can't be provided.
In view of this, how designing a kind of touch control display, can provide the hand-written induction touch control manner of controlling to write and control the induction touch control manner with pen simultaneously, select to use for the user, is the problem that those skilled in the art need solution badly.
Summary of the invention
In prior art, display has only the single induction touch control manner of controlling, and can not be as required selects the defective that exists to controlling the induction touch control manner, the invention provides a kind of touch control display.
According to the present invention a kind of touch control display is provided, comprises first substrate, chromatic filter layer, second substrate, liquid crystal layer, a plurality of first inductor, a plurality of second inductor, first Polarizer, second Polarizer and module backlight.Chromatic filter layer is positioned on the lower surface of first substrate, comprises the resistance of a plurality of pixels and a plurality of look, and each look resistance lays respectively between adjacent two pixels.The corresponding setting of second substrate with first base lower surface.Liquid crystal layer is located between first substrate and second substrate.A plurality of first inductors are positioned on the upper surface of first substrate, and signal is sent in the variation of ability inductive reactance, and the spacing of being separated by between each first inductor.A plurality of second inductors are positioned on the upper surface of second substrate, can respond to infrared light sending signal, and each second inductor is corresponding to resistance of all kinds.First Polarizer is positioned on a plurality of first inductors.Second Polarizer is positioned on the lower surface of second substrate.Module backlight is arranged at the below of second Polarizer.
Preferably, second inductor is an infrared inductor.
Preferably, a plurality of photoresistances can let infrared light see through.
Preferably, module backlight comprises a light source.
Preferably, light source is a white light LEDs.
Adopt advantage of the present invention to be: touch control display has electric resistance touch-control induction mode and infrared touch control light source mode simultaneously, selects when needed to be suitable for for the user.
