10. Contd…
 Metal halide lamp is emitting the light.
 Series of di-chroic filters are separates light.
 3 polysillicon panels placed in red, blue, green color's
 These primary color's are making the image.
 Metal halide lamps are output an ideal color temperature.
 LCD technology is used by many manufactures such as Epson,
Hitachi, and NEC.

11. Advantages of LCD
 LCD is generally more light efficient than DLP.
 3LCD projectors can project bright, vivid images with a low
output lamp.
 1000 lumen LCD is more preferred than 1200 lumen DLP .
 LCD trends to produce a sharper image.
 More accurate color.
 Sharper image
 More light efficient.

12. Disadvantages
 More bulky as there are more internal components.
 Dead Pixels.
 LCD panel can fail
 Screen door effect.
 Contrast.
 Portability.
 Image degradation.

13. DLP projectors.
 DLP-Digital Light Processing.
 Worlds only all-digital display solution.
 DLP technology is based on semiconductors called DMD chips.
 Invented in 1987 by Texas.
 DMD chips made up of many tiny mirrors.
 Current DMD chip can produce 1024 shades of grey.
 Found in projectors manufacturers of BenQ ,InFocus and Optoma.

14. Advantages
 Portability.
 Higher contrast.
 Reduced pixilation.
 Reliability.
 Sealed optics this makes it better for use in dusty
environment.
 Less screen door effect.
22/02/17 14M S QAISAR

15. Disadvantages
 Rainbow effect.
 Light leakage.
 High cost.

16. Laser keyboard
(virtual keyboard)
 A Virtual Keyboard is a projection keyboard that is projected and
touched on any surface
 User operates by typing on or within a wireless or optical
-detectable surface or area rather than by depressing physical keys.
 Proved nightmare for users
 Way to eliminate finger cramping
22/02/17 16M S QAISAR

17. What Actually it is
 Keyboard that a user operates by typing (moving fingers) on or
within a wireless or optical-detectable surface or area rather than
by depressing physical keys.
22/02/17 17M S QAISAR

18. Technologies Used
 In one technology, the keyboard is projected optically on a
flat surface and, as the user touches the image of a key, the
optical device detects the stroke and sends it to the computer.
 In another technology, the keyboard is projected on an area
and selected keys are transmitted as wireless signals using
the short-range Bluetooth technology.
 With either approach, a virtual keyboard makes it possible
for the user of a very small smart phone or a wearable
computer to have full keyboard capability.
 Theoretically, with either approach, the keyboard can be in
space and the user can type by moving fingers through the
air!

19. Reasons to use the virtual
keyboard.
 When connected to your handheld computer it is more convenient
to carry around than your laptop.
 It takes up less desk space than a conventional keyboard.
 You could use it with your desktop, laptop or handheld computer.

20. Advantages
 Portability
 Accuracy
 Speed of text entry
 Lack of need for flat or large typing surface
 Ability to minimize the risk for repetitive strain injuries
 Flexibility
 Keyboard layouts can be changed by software allowing for foreign
or Alternative keyboard layouts.

21. If there is no wall?
 When we are working in an
open place we can make use
of a paper sheet as a screen.
 paper sheet holder is placed
at the back panel of this
computer.
 The holder can be opened by
pressing it in the lower part

26. Conclusion
 As years passes, the computer size is becoming smaller.
 Today’s technology is at its peak point beyond what we could
ever imagine.
 New inventions and innovations are emerging on daily basis.
 Our imaginations have dressed into reality and today it has
become possible to have a whole computer in our pocket all
the time. This ball computer has taken the computer
technology to new horizons.
