Description
Technical Field
The utility model relates to a display screen industry specifically is an IPS electric capacity touch display screen that transmission distance is far away and interference killing feature is strong.
Background
Present parallel port RGB display screen needs more IO mouth, and signal transmission rate is low, and transmission distance is short, and the interference killing feature is relatively weak, traditional electric capacity touch display screen, and liquid crystal display signal and touch-sensitive screen signal transmit through solitary interface, for further reducing the transmission cable, the lowering system consumption increases transmission distance and interference killing feature, need to develop a transmission distance far away, low-power consumption and the strong electric capacity touch display screen of interference killing feature urgently.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a transmission distance is far away with IPS electric capacity touch display screen that the interference killing feature is strong to solve the problem that provides in the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a transmission distance is far away with IPS capacitive touch display screen that interference killing feature is strong, includes TFT display screen and two twisted pair cables capacitive touch screen is installed to TFT display screen top electrical property the PCB drive plate is installed at TFT display screen back be provided with two twisted pair cable connectors on the PCB drive plate still be provided with the component area on the PCB drive plate.
Compared with the prior art, the beneficial effects of the utility model are that: this device converts liquid crystal drive signal into LVDS interface transmission, and liquid crystal drive signal and touch drive signal integration have reduced transmission cable quantity on an interface, adopt the transmission of paired line, and transmission distance is far away, the system consumption is low, and the interference killing feature is strong, has higher practicality and market prospect, is fit for using widely on a large scale.
