V780-V Electronic Viewfinder EVF 1080P VGA Interface Adjust Brightness Contrast Powered Via USB

What is electronic viewfinder?
Electronic viewfinder EVF requires power when working. It is similar to an LCD display, and is mainly used for viewing the shots and viewfinders when shooting with digital cameras and digital video cameras. The content displayed on the LCD of a general digital camera can be displayed on the electronic viewfinder (EVF).

The electronic viewfinder is a combination of a miniature OLED display and a driving circuit, with an optical lens of appropriate multiples. Because the electronic viewfinder uses more comfortable optics and an additional light-shielding goggles, the external light cannot shine on this miniature OLED screen, and the display effect of the large screen is imaged through the optical eyepiece, so the field of view using the electronic viewfinder is larger than that of the optical viewfinder. Electronic viewfinders are more practical, cheaper, and can be used in any ambient light. The electronic viewfinder can display the full picture of the scene to be photographed, and can display shooting information such as aperture and shutter speed. In addition, it can also display a menu, which is not possible with other viewfinders.

V780-V Description:
V780-V adopts digital display technology to image 1080P video without attenuation. It uses an OLED display, an optical eyepiece equipped with a 22MM pupil (supports diopter adjustment 0-400° for myopia), and a HD digital processing chip supports brightness and contrast adjustment. V780-V is a VGA interface: two external lines respectively, one is a USB line, and the USB line is mainly for external power supply. The V780-V portable display does not have a built-in battery, so an external power source is required.

V780-V is a portable large-screen HD display, display 80 inches, 1024*768 active matrix color. 0.5-inch OLED panel module uses monocrystalline silicon transistors. The panel adopts panel drive and logic drive, and features small size, light weight and high definition.

Applications:
1. In simulation command training system: With a HD large-screen external monitor, you can independently observe the situation of each team member. At the same time, it does not affect the display of the large screen of command system. After each evaluation examiner can appropriately adjust the brightness, contrast and myopia. It is small in size, small in power supply, anti-shock and anti-fall, and with a large HD screen.
2. In photography industry: In the camera industry, most of the external 7-inch screens are currently used. The disadvantage of the external 7-inch screen is that it is not light-proof and has low visibility under strong light. V780-V uses a hood with a built-in large-screen HD display, can effectively prevent this problem. The resolution of 1024*768 is exactly the video rate output by camera, and real video is displayed digitally without distortion. Its small size, low power consumption and easy portability make it popular among many users.
3. In the medical industry: The external displays of desktop medical equipment such as ultrasound, X-ray machines, endoscopes, etc., and the built-in displays of medical industry equipment have relatively low resolution. With the development of science and technology and the advancement of visual technologies such as medical detection and perspective, there is an increasing demand for HD portable large-screen external displays. Its unique concealment effectively protects personal privacy.
