ประวัติความเป็นมาของโปรเจคเตอร์Magi

The history of the projector.Magic Lantern or Lanterna Magica is considered to be the earliest ancestor of the era of the projector. In 1671 Athanasius Kircher, German scientists have explained the concept of projection equipment with tubes for oil as fuel. The lens and the image is drawn to the projector in order to phaenkrachok on the screen.Projector (Projector) is the projection equipment that is used to convey information, with photos from the computer signals can be supported, VCD player, DVD player, and other image generator.Advantages and disadvantages of LCD projectorsThe advantages of LCD System. 1. live color saturated and bright 2. high contrast Disadvantages of LCD System. 1. low Contrast Ratios are up. 2. cannot convey the depth of shades of black. 3. to display the color of clouds, smoke (as infection). Advantages and disadvantages of a DLP projectorThe advantages of DLP systems. 1. provide the stunning colors. A very good level of colours 2. the picture will look soft and slick. 3. High Contrast Ratio, 4. high bulb life Disadvantages of DLP systems.1. There may be a problem in some sparkling Rainbow.The difference of dual projectorOur objective is to see the tablet screen or image Pixel boundaries of the chitkwa of the DLP LCD due to the technological processes generate a DLP projector makes a better LCD picture.Using the projector with the computer.How to turn on the device. 1. first, open your (UPS) to maintain a constant level of power, and power is reserved while power failure suddenly.2. Start the computer. 3. turn on Projector using remote control to the front or rear Projector machine during the presentation through the Projector if the Projector should be shut down, the lecture room to extend the service life of tubes.4. open the Power Amplifiers.5. adjust the Volume level of the audio to no more than 3 levels.How to adjust the projection level. 1. press the Elevator (lift). 2. raise the projector to the desired angle, and then release the button to raise the leg of the rock, where the. 3. use adjust the tilt to adjust the projection angle appropriately.How to turn off the device. 1. turn off the power by pressing the remote control point the Projector at the front or rear Projector (wait for the flashing machine on the Projector changes from red to green, the fan of the air cooling of the tubes. Protect tubes swelling or lack).2. adjust the sound Volume level 0.3. turn off the Power Amplifier.4. turn off your computer, follow the steps.5. after closing the Projector and do not need to turn off your lights (UPS) so that the fan is working and the fan will stop when the heat reduction.Cleaning the projector1. in order to eliminate stains that have dust. Wipe the machine with a clean cloth.2. in order to eliminate the stains with a smudge that persist, use a soft cloth dampened in water mixed detergent with pH neutral-dampened cloth to wipe and then twist to clean.To clean the lens.1. use spray dust blown soda out. 2. If there is a stain or smudge, wipe the lens or the paper used a lens cleaner on a soft cloth and then wipe the droplets onto the lens surface gently.

The history of the projector
or Magic Lantern Lanterna Magica is an early ancestor of the projector when the year 1671 a German scientist Athanasius Kircher explained the concept of a device for projecting a lamp that is used as a fuel. fuel The lens and the image is drawn on a sheet of glass to project the image onto a screen
projector (Projector) is projecting equipment used in presenting information. It supports video input from a computer, VCD, DVD, generators and other imaging
advantages and disadvantages of the projector. LCD
advantages of LCD
color saturation and vivid relay 1.
2. A high contrast
disadvantages of LCD
1. Contrast Ratios are under
2. can not convey the depth of the shade of black was
third. There are problems in the rendering of clouds, smoke (a gun) Advantages and Disadvantages of projectors. DLP DLP system advantages 1. the colors are stunning. The Gradation very good second. The image is soft and silky 3. Providing high Contrast Ratio of 4. Lifetime lamp height disadvantage of DLP systems may have flashed rainbow 1. In some models the difference of the two projectors is the obvious thing is the boundaries of the dot or point. Photo Pixel DLP over LCD's proximity to the technological process. Therefore, when creating an image. DLP projectors, the image and smooth over. LCD projector for use with a PC to the device first. First, open the UPS (UPS) in order to maintain a constant power level. And a sudden power outage while power 2. Start the computer 3. Open Projector using the remote control pointed at the front or rear Projector Projector If the presentation through a lecture room. Projector should shutdown to prolong the lifetime of the lamp 4. Open amplifier by pressing the Power 5. Volume adjust audio volume to a level not exceeding level. 3 way adjustable projector 1. Press the Elevator (superscript) 2. Raise the projector to the desired angle. Then release the button to. Rock legs of the lift to the desired position 3. Use the tilt adjustment wheel To adjust the projected image to the right to turn off the device first. Projector is turned off by pressing the remote control pointed at the front or rear Projector (wait for the flashing lights on the machine Projector change from green to red. For fans of the cooling of the lamp. Lamp prevent swelling or lack of) two. Volume adjusts the sound to return to the level 0 3. Turn off the amplifier by pressing the Power button 4. Turn off the computer Step 5. After closing Projector do not need to shutdown UPS (UPS) to keep the fan running. And fans will stop when the heat down to clean the projector 1. To remove stains with dust. Wipe the machine with a cleaning cloth 2. To remove stains with a stain ingrained. Use a soft cloth dampened with a neutral pH detergent and water, then wring the cloth to wipe clean the lens first. Use a spray of sparkling dust out two. If there is dirt or smudge. Use paper towels or lens Use drip lens cleaner on a soft cloth and wipe the surface gently.
