Acer dynamic RGB gain control - Secure color fidelity  Acer Dynamic RGB Gain Control, detects any subtle changes that causes color decay, then use control techniques to adjust the RGB output to secure better color fidelity than LCD and other DLP ® projectors E.g. After 1000hrs

ACER CONFIDENTIAL ColorSafe II Technology – Reliable image quality III. Advanced lamp technology- Keep the brightness level constant  With Philips and Osram’s innovative lamp technology, Acer projectors become a better solution for education usage The first day performance ColorSafe II Technology: Constant brightness for 2,000 hours Normal operation: Brightness decay severely for 2,000 hours 2,000 hours

ACER CONFIDENTIAL LumiSense+ 13

ACER CONFIDENTIAL 14 Ambient light conditions keep on changing. It’s tiresome to repeatedly adjust color and brightness for different light conditions…

ACER CONFIDENTIAL 15 Want a projector that can smartly adapt to different light conditions? LumiSense+ makes it come true.

ACER CONFIDENTIAL 16 Dark environment Well-lighted room LumiSense+ LumiSense + delivers the best viewing experience no matter if it’s in a well-lit room or dim environment. Ambient Light Sensor With an embedded light sensor, a projector can detect ambient light conditions and the LumiSense + computing engine then dynamically optimizes projected image brightness levels and color saturation accordingly. Content- Aware Process In addition to image optimization based on ambient light, LumiSense+ has clever content-aware technology which also analyzes projected content frame by frame and dynamically adjusts image visibility to the optimum level.

ACER CONFIDENTIAL sRGB 18

ACER CONFIDENTIAL 19 Does this problem ever bother you? The Carol dress on your laptop becomes drab when projected… Color is inconsistent across devices

ACER CONFIDENTIAL 20 sRGB is a color standard. It ensures color consistency between projectors and other devices.

ACER CONFIDENTIAL 21 sRGB sRGB is an industry color standard that is widely utilized by monitors, printers, cameras, smartphones, throughout Internet, and now by projectors. sRGB Standard sRGB meets the following three criteria Color Gamut 72% NTSC Gamma % NTSC color gamut is 130% higher than a conventional lamp projector’s color gamut 6500K color temperature produces genuine color with natural tones Gamma 2.2 generates a clear image with great contrast 6500K Color temperature Gray level CIE chromatic diagram coordinate 6500K Wx 6500K Wy

ACER CONFIDENTIAL 22 sRGB mode Non-sRGB sRGB The use of sRGB mode guarantees color consistency and eliminates deviation in color reproduction. Project photos, video, movies, or any content with faithfulness to their original color. Color deviation from other devices Color compliant across devices Color consistency Even Epson printers adopt sRGB standard.

ACER CONFIDENTIAL ColorPurity 23

ACER CONFIDENTIAL 24 Do you ever wonder why colors look flat on a screen?

ACER CONFIDENTIAL 25 ColorPurity produces pure RGB and generates more color levels.

ACER CONFIDENTIAL ColorPurity 26 Combining an RGBRGB color wheel, lamp control technique on multiple waveforms and a unique software engine, ColorPurity produces a wider color gamut of 72% NTSC. It generates uncompromised visuals with more pure and abundant color. Non-RGBRGB 55% NTSC color gamut Improve color wheel segment & coating Get more purer RGB color 72 % NTSC color gamut RGBRGB Color Wheel

ACER CONFIDENTIAL ColorPurity 27 Pure color with abundant color gradations Pure Color Because of the wider color range, color can reach its most pure level. Green becomes extremely green, red is pure red and blue is amazingly blue. Abundant Color Level Thanks to an expanded color range, a projector presents images with abundant color gradations. Flowers can be peach puff, light salmon, coral and rosy brown, instead of only one kind of pink.
