Description

Touch screen LCD
[technical field]
The invention relates to a kind of LCD, particularly about a kind of touch screen LCD.
[background technology]
Because advantages such as LCD has gently, approaches, power consumption is little are widely used in modernized information equipments such as TV, notebook, computing machine, mobile phone, personal digital assistant.In order to dwindle the volume of personal digital assistant, the LCD that is used for personal digital assistant combines with touch-screen usually to omit key panel or function button, and touch-screen is used to control the image demonstration of LCD and realizes function control by touch-control generation electric signal usually.
A kind of touch screen LCD of prior art can be consulted Fig. 1, and this touch screen LCD 100 comprises that a touch-screen 101, is pasted and is with 105, one display panels 102, one first flexible circuit board 103, one second flexible circuit board 104 and a main circuit board (figure do not show).This display panels 102 comprises a display driver chip 106, and this is pasted and is with 105 this display panels 102 pasted into an integral body with this touch-screen 101.This main circuit board comprises a touch-screen chip for driving (figure does not show) and two connectors (figure does not show), this touch-screen chip for driving is used to resolve the electric signal that this touch-screen 101 produces, and this display driver chip 106 provides these display panels 102 work required driving voltage.One end of this first flexible circuit board 103 is electrically connected to this touch-screen 101, and an other end is connected to this touch-screen chip for driving by this connector.One end of this second flexible circuit board 104 is electrically connected to this display driver chip 106, and the other end is connected to this main circuit board by this connector.
Because the touch-screen 101 of this touch screen LCD 100 is connected to this touch-screen chip for driving that is positioned on this main circuit board by first flexible circuit board 103 by connector, this display panels 102 is connected to this main circuit board by this display driver chip 106 by this second flexible circuit board 104, the touch-control signal transmission channel of this touch-screen is two signalling channels of separating with the transmission channel of liquid crystal display-driving signal, first, second flexible circuit board all needs connector to be connected to this main circuit board, therefore structure is complicated, and ease of connection is loosening, can not adapt to touch screen LCD and be tending towards demand simple in structure.
[summary of the invention]
Be the baroque problem of the touch screen LCD that overcomes prior art, provide a kind of touch screen LCD simple in structure real for necessary.
The technical scheme that a kind of better embodiment discloses is: a kind of touch screen LCD, comprise a touch-screen, a display panels, one first flexible circuit board, one second flexible circuit board and a main circuit board, this display panels comprises many leads and is electrically connected a slice control chip of these many leads, this control chip provides this display panels work required driving voltage, and resolves the electric signal that this touch-screen produces; One end of this first flexible circuit board is electrically connected to this touch-screen, and an other end is connected to this control chip by many leads on this display panels; One end of this second flexible circuit board is electrically connected to this control chip, and the other end is connected to this main circuit board.
Compared to prior art, because the touch-control signal that the touch-screen of touch screen LCD of the present invention produces transfers to this control chip earlier and resolves, transfer to this main circuit board by this second flexible circuit board then, omitted the connector between this first flexible circuit board and this main circuit board and touch-screen chip for driving on this main circuit board in the prior art, therefore touch screen LCD of the present invention is simple in structure.
[description of drawings]
Fig. 1 is a kind of synoptic diagram of prior art touch screen LCD.
Fig. 2 is the side view of the disclosed a kind of touch screen LCD of better embodiment of the present invention.
Fig. 3 is the vertical view of touch screen LCD shown in Figure 2.
[embodiment]
See also Fig. 2 and Fig. 3, Fig. 2 is the side view of the disclosed a kind of touch screen LCD of better embodiment of the present invention.Fig. 3 is the vertical view of touch screen LCD shown in Figure 2.This touch screen LCD 200 comprises that a touch-screen 201, a display panels 202, are pasted and is with 205,1 first flexible circuit board 203, one second flexible circuit board 204 and a main circuit board (figure do not show).This display panels 202 comprises many leads 209 and is electrically connected a control chip 206 of these many leads that this control chip 206 provides these display panels 202 work required driving voltage, and resolves the electric signal that this touch-screen 201 produces; One end of this first flexible circuit board 203 is electrically connected to this touch-screen 201, and an other end is connected to this control chip 206 by the many leads 209 on this display panels 202; One end of this second flexible circuit board 204 is electrically connected to this control chip 206, and the other end is connected to this main circuit board.This is pasted and is with 205 between this display panels 202 and this touch-screen 201, and it pastes this touch-screen 201 and these display panels 202 structures in aggregates.
In addition, these many leads 209 can be plain conductors or be made of tin indium oxide conductive film (ITO) in the touch screen LCD of the present invention.This first flexible circuit board 203 is to be electrically connected with many leads on this display panels by anisotropic conductive (ACF) or alternate manner, and this touch-screen 201 can be any one in pressure sensing type touch-screen, optical profile type touch-screen, electrostatic capacity type touch-screen and the ultrasonic formula touch-screen.
Compared to prior art, should in the touch screen LCD that the present invention adopts The touch-control signal that touch-screen produces is transferred to earlier this control chip and resolves, then Be transferred to this main circuit board by this second flexible circuit board, omitted prior art In connector and this main electricity between this first flexible circuit board and this main circuit board Touch-screen on the plate of road drives chip, therefore touch screen LCD of the present invention Simple in structure.
