Description
[technical field]
The utility model is about 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 10 comprises a module 110 backlight and a display panel 100.This module 110 backlight comprises a light guide plate 112 and a backlight 114.This display panel 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.This module 110 backlight provides light source for this display panel 100.
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 touching signals 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.
[utility model content]
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.
A kind of touch screen LCD, it comprises a module backlight and a display panel.This module backlight comprises a backlight and a light guide plate.This display panel comprises 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 a control chip that is electrically connected with these many leads, and 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 touching signals that the touch-screen of above-mentioned touch screen LCD 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, so this touch screen LCD is simple in structure.
