2nd, the acquisition of the touch trajectory of the utility model system is unrelated with currently used multiple different operating systems.
The utility model is described in further detail below in conjunction with drawings and Examples, but a kind of guarantor of the present utility model
The interactive TV system of shield operator's eyesight is not limited to embodiment.
Brief description of the drawings
Fig. 1 is the entire block diagram of the utility model system.
Embodiment
It is shown in Figure 1, a kind of interactive TV system of protection operator's eyesight, including interactive television, the friendship
Mutual formula TV includes touching display screen 1, MCU processors 2, main control chip 3, backlight 4 and the light sensation mould for running android system
Block 5, the touching display screen 1 includes the touch frame 11 and display screen 12 by electrically connecting；The MCU processors 2 are touched with described
Frame 11 is controlled to be connected；The main control chip 3 is connected with the MCU processors 2；The main control chip 3 and the phase of light sensation module 5
Even；The main control chip 3 is connected with the backlight 4；The backlight 4 is connected with the display screen 11 and positioned at the display
The rear of screen 11.
Specifically, the touch frame 11 includes UART interface and USB interface, the MCU processors 2 include two UART interfaces
