[Embodiment] 200904115 See the figure 2, which is the touch display device of the present invention, the touch-screen display device 2 includes a touch unit 2, a display unit 22, and A display control unit 23. The display unit 22 includes a liquid crystal display panel 221 and a north group of milk, and the backlight module 222 provides sufficient backlight for the liquid crystal display: surface = 221 for image display. A touch screen 211, a converter 212, a process 213, and a touch screen driver 214. The touch screen drive interface 4 is used to drive the touch screen 211. The touch screen 211 is driven by the touch actuator 214. An external pressure signal is transmitted to the converter 212. The converter 212 changes the pressure to a digital position signal indicating the pressure position, and transmits the number::: signal to the processing The processor 213 processes the digitized position signal, and transmits the position signal to the liquid crystal display panel 221 for display, or performs related operations on the touch display device 2. The detection control unit 23 includes a controller 231, a light sensor, and a singularity 2 3 3. The suffix 2 3 3 is a memory that can be read and written multiple times, and stores the working state of the touch display device 2 Corresponding relationship of the external environment ί line change, wherein the working state of the touch display device 2 includes a positive working state and a non-working state. The light sensor 232 detects the external ambient light change of the touch display device 2, and converts the outer ring=light wheat into a signal signal and transmits the signal to the controller. The control benefit 231 compares the stored data of the memory 233 when receiving the change of the external light detected by the photo sensor 232, thereby determining whether the extinction display device 2 is in a normal working state or a non-working state. And according to its working condition of 10 200904115, turn on or off the touch unit 21 κ. 4 touch screen driver 214, and then turn on or off: the specific working method of the touch display device 2 is as follows: 1. Setting Detection parameters; 232 two = two: gas" manufacturers according to the habit of setting the light sensor environment light changes in the clothing line in the middle of the second line of Ginseng to accurately detect the external ring detection, measurement frequency and so on. - the relevant worm number may be the detection interval time, 2. the correspondence between the change of the ambient light and the working state; the touch =: detecting the relationship between the external ambient light change result and the " The memory 233 has two working hours, the detection frequency, the detection position, and the external first line 7C degree and the change rate. 3. detecting the change of the external ambient light; starting the photo sensor 232, according to the set frequency: the number: the change of the ambient light of the Bu' and converting the ring: light == into a signal to the controller 231 . 4, comparing the ambient light with the preset condition, issuing a control command; the controller 231 receives the ring light change detected by the light sensor 232: the signal, and finds the preset ambient light _ result in the memory 233 Corresponding relationship table of the state, finds the state of the touch display device '2 and the outside: ambient light change, and according to the work state, the ground is out: corresponding control command to the touch screen driver 2U. For example, when the touch ' = No device 2 is placed in a pocket, drawer, etc., the ambient light is dimmed, indicating that the touch display device 2 is in a non-working state, the controller 231 11 200904115 issues a shutdown control command when the ambient light continues to be in time The change indicates that the UI touch display device f 2 is in a normal working state, and the controller 23 issues an open control command. 5. Adjusting the working state of the touch unit 21 according to the control command. The touch screen driver 214 receives the change. The controller 231 outputs a control command, and adjusts the working state of the touch unit 21 according to the command. In the case, when the control command is off, the touch screen driver 214 turns off the f control. The touch unit 21 stops working. At this time, the touch screen 2 ι does not respond to the external pressure; when the control command is on, the touch screen drives the stomach 214 to drive the touch unit 21 to work, and the touch #2ιι responds to external pressure. The corresponding operation of the touch display device 2, the detection, p, and the other of the touch display device 2, the light sensor 232 controlling the early detection 23 detects the touch display device You „„ ^, 衣复2 work environment changes in light, the control is 231 according to the § Haiguang sensor 232 accounted for the detection results of the Japanese ^ ^ ^ ^, the comparison is preset

The sampling unit is said to be a horse, which detects the switching state of the backlight module 322, converts the off-state into a digital signal, and transmits the signal to the sweat control. The signal includes a backlight activation and a backlight shutdown. Receiving the digital signal and rotating the touch screen driver 314 of the touch unit 31 according to the switch state of the light to: the working state of the touch screen driver 314. ^ μ The specific working method of the touch display device 3 is as follows: The backlight module 322 of the display unit 32 is turned on: the control display device 3 is in an active state, and the sampling unit 332 takes the backlight signal that is turned on first. And issuing a representative;; 331. The controller 331 analyzes the first signal to the touch screen driver 3U, and activates the touch screen driver: the touch screen driver M4 drives the touch screen 311 to operate. =:Touch# 3U can receive the external pressure signal and external pressure gas: = The converter 312 and the processing core are processed by 1 °卩力力#U, and the position signal transmission panel 321 is displayed, or According to the pressure signal, the related operation is performed on the right touch display device 3. When the backlight module 322 is in the off state, the touch display device 3 is in a wide state, and the sampling unit 332 sends a representative non-working state. The signal is sent to the controller 331. The control $331 analyzes the second issue-off signal to the touch screen driver 314, and the screen driver 314 is turned off. The touch screen driver 314 stops driving the touch 13 200904115 screen. 311, at this time, the 觫ττ ^ ^ ^ ^ 4 蜀 button 311 does not react to the external pressure signal, and the touch display device 3 is also touch-operated.
