摘要:
The invention provides a touch module and an operation method thereof. The operation method of touch module includes following steps: detecting a touch point; judging whether the touch point is normal touching according to a detected result of the touch point; when the touch point is abnormal touching, reducing the intensity of an infrared laser of the touch module; and when the touch point is normal touching, judging out the position of the touch point. By using the operation method of touch module, it can reduce or avoid the injury of the infrared laser on the vulnerable portions of human body as abnormal touching.

A projection device and an automatic projection calibration method thereof are disclosed. When the projection device boots up, an image pattern corresponding to a display data is projected through a projecting unit. The image pattern is sensed through an image sensor to obtain information of the image pattern. The information of the image pattern is compared with information of a previous image pattern through a processing unit to determine whether to execute an automatic calibration procedure. When the processing unit executes the automatic calibration procedure, a calibration pattern is projected through the projecting unit. The calibration pattern is sensed through the image sensor to obtain information of the calibration pattern. A calibration driving procedure is executed through the processing unit to convert imaging coordinates of the calibration pattern sensed through the image sensor into projecting coordinates of the projection device, so as to establish a coordinate conversion table.

摘要:
A rear projection display device includes an image generator, a reflector, a screen and a light shield disposed between the reflector and the screen. The image engine emits image beams among which ineffective ones are blocked by the light shield while effective ones are reflected on the screen via the reflector, thereby increasing the image forming performance of the displace device. The light shield is mounted on an adjusting device having an adjusting element. After the rear projection display device has been assembled, an angle and position of the light shield can be adjusted by means of rotating the adjusting element to further help the light shield to block the ineffective beams.
