Abstract

The invention discloses a remote-control video display bench for teaching. The display bench comprises a base with a backlight plate. An LCD video monitor and a control bench with a built-in rechargeable power supply are arranged on the base. The LCD video monitor is connected with the control bench. An infrared receiving device is arranged on the control bench and is connected with an infrared remote controller. A desk light neck which can be twisted and bent is fixed on the top of the control bench and a machine head is fixed to the desk light neck. A CCD lens is disposed on the end of the machine head. Light supplement lamps with desk light necks are arranged on two sides of the control bench. The display bench uses the desk light necks to replace complex mechanical structures for stretching and retracting, so that the bench is simpler than other similar products in structure. Besides, the display bench is provided with the built-in rechargeable power supply, so that no long connection line is needed during teaching, and thereby usage in teaching is greatly facilitated.

Description

technical field [0001] The invention belongs to the technical field of teaching equipment, in particular to a video display stand. Background technique [0002] Common scanners currently on the market are generally CCDChargeCoupledDevice and photoelectric coupled sensor scanners according to the different photoelectric conversion elements. It focuses on the CCD through the lens, converts the light signal into an electrical signal image, and the latter is close to the surface of the scanned manuscript for contact scanning. The CCD scanner focuses on the CCD through the lens and directly senses the light, which can be very convenient for physical scanning. The photosensitive device CCD in the scanner is a relatively mature technology. Its cost is relatively low, but the imaging quality is getting higher and higher. The CCD using silicon single crystal technology has lower requirements on the ambient temperature and has a wider range of adaptation. With the development of te...
