ts = touchscreen.TouchScreen()
x, y, pressed = ts.read()
```

## 样例程序

```python
from maix import touchscreen, app, time, display, image

ts = touchscreen.TouchScreen()
disp = display.Display()

img = image.Image(disp.width(), disp.height())

def menu_update(img):
    img.draw_string(8, 12, "< Exit", image.COLOR_WHITE)
    img.draw_rect(0, 0, 100, 100,  image.COLOR_WHITE, 2)

while not app.need_exit():
    x, y, pressed = ts.read()
    if x > 0 and x < 100 and y > 0 and y < 100:
        app.set_exit_flag(True)
    
    menu_update(img) # 更新菜单
    disp.show(img)   # 屏幕显示
```
