In dash DVD player

The in dash DVD player has become the industry standard in automotive multimedia entertainment. In dash players don’t necessarily include in dash screens. Often, the DVD player is mounted in the dash then sends the signal to screens in the rear of the vehicle. Other types of DVD players are mounted underneath seats or in the trunk of an automobile. Because they make loading and unloading disks less convenient they are not as popular.

An in dash DVD player which does include an in dash screen may allow the screen to double as a virtual instrument panel or GPS navigational tool. This makes them especially useful for drivers since watching a movie while managing a vehicle is generally not a fantastic idea. Dash-mounted Liquid Crystal Display (LCD) screens in conjunction with back-up cameras to help those who don’t understand how mirrors work. In dash screens are convenient for front-seat passengers and drivers on long trips as they allow for entertainment, weather updates and driving directions when not on the road.

There are several makes and models of automobiles on the market that include DVD players as standard equipment. Many of them include multiple screens, allowing for passengers to be entertained independent of one another. Gone are the days of magnetic board games, playing cards and other forms of interactive travel entertainment. For those who still long for such interaction, LCD screens can be used to play video games when DVDs get boring. Satellite television is growing in popularity at home and on the road. Multiple headphone jacks allow passengers to simultaneously listen to the same program or different programs, if they choose.

The omnipresence of the in dash DVD player can be largely attributed to advances in the Liquid Crystal Display world. LCD screens are used in virtually every automotive multimedia entertainment system. They are also used throughout the world in home entertainment systems, computers and thousands of other appliances and applications. Liquid crystals are the key to a relatively new technology that has only been relevant for about the last thirty years. Scientists discovered the crystalline nature of specific liquids more than a century ago but they could not imagine a practical application at the time.

It was not until 1970, when a phenomenon known as the twisted nematic field effect was discovered, that people began discussing real-world uses for liquid crystals. The discovery and development of the phenomenon allowed liquid crystals to be manipulated using very little outside energy. Prior to the finding scientists had been able to control crystals to a certain degree but not nearly enough to use them effectively . LCD screens used in car DVD players and other devices still rely on the twisted nematic crystal effect today. Shortly after its discovery, a Japanese company introduced the world’s first liquid quartz wristwatch and an industry was born.
