The liquid crystal used in display technology such as LCD/LED monitors, large format display or digital signage is driven by electrodes.
If the same display is remained at the same position for a long time, electric charge driving the electrodes can cause liquid crystal to build up and remain in one position, leaving a mark. This mark or residue as a result of image retention is usually a shadow, or faint outline of the previous static image that was being displayed.
Image retention is when an image temporary or permanently remain or "burn" onto the LCD/LED panel.
To have stable brightness output, it should keep the lamp working temperature in a range only around 50 degrees.
So the thermal system for a projector is very important These lamps can be purchased through authorized audio-video dealers or from Ben Q.
To avoid image retention, please activate the power management function to let the LCD/LED monitor, large format display or digital signage go into "sleep mode", or turn on screensaver after short period of inactivity.
Alternatively, can use animation to avoid same display is remained for a long period of time.
There is a standard measurement of the pixel damage allowed if it is due to the DMD damage. If there is a uneven dark spot on the display, There are black substrates around the mirror of the DMD chip. The light bulb of the projectors with general metal bulbs has its special-purpose specification, suitable for this factory model only and unable to share with other factory brand.
The black frames around the display area are the reflection of the black substrates from the lights. Therefore, not being able to have mass production results in its expensive Because the working temperature of projectors is between 300~950 degrees.Otherwise, the control circuitry in the projector cannot tell what kind of signal it is, especially sync signals.If a video amplifier is not used, image The noise that users hear normally came from: 1.However, MP770 and SP series has the hot key on the remote and user can change it very easily.For MP6 &7 series, they need to buy the special RS232 cable (optional) from Ben QThe life-span of light bulbs used in the projector can be categorized as 1500, 2000, and 3000 hours.And the Ballast can translated the energy from the power supply to the lamp.
