1 Jan Shift + F5 for Slides Display for Next Page for Back Page Shift + F5 for Slides Display for Next Page for Back Page Transparent Frame (Active Bezel) Transparent Frame (Active Bezel) Seamless LCD

2 4 TYPES OF VIDEO WALLS 3) LED – Light-Emitting Diode (Self-Lighted) 1) DLP – Digital Lighting Process (Back Projection) 2) PDP – Plasma Display Panel (Self-Lighted) 4) LCD – Liquid Crystal Display (Back-Lighted)

3 LCD Characteristics 3) LCD is higher reliability - It usually falls into outdate before it stops working 3) LCD is higher reliability - It usually falls into outdate before it stops working 1) LCD is a maturity industry with huge industry chains 2) LCD is the king of display - Everybody takes LCD, usually takes more than one of them - Everywhere is spread by LCD, house, office, public building 2) LCD is the king of display - Everybody takes LCD, usually takes more than one of them - Everywhere is spread by LCD, house, office, public building 4) LCD size is becoming larger and larger - Today, the largest size of LCD is 120 inches, though its hard to be shipped 4) LCD size is becoming larger and larger - Today, the largest size of LCD is 120 inches, though its hard to be shipped 5) Resolution of LCD is going to be 4,000 (4K) - A Full HD could be easily made in a size of mobile phone - In other words, a size of 4 mobile phones will reach 4K resolution 5) Resolution of LCD is going to be 4,000 (4K) - A Full HD could be easily made in a size of mobile phone - In other words, a size of 4 mobile phones will reach 4K resolution 6) LCD is Lower Power Consumption with Long Life - Power Consumption is about 260 w/m 2 - Working Life is over 60,000 hours 6) LCD is Lower Power Consumption with Long Life - Power Consumption is about 260 w/m 2 - Working Life is over 60,000 hours

4 A Typical DLP Body 650 ~ 815 mm 650 ~ 815 mm Higher Maintenance and Larger Space required Pixel = 1024 x 768 Brightness = 225 ~ 300 cd/m 2 Brightness = 225 ~ 300 cd/m 2 Required Back Space at 1 m Required Back Space at 1 m Suitable to A Dimmer Room Suitable to A Dimmer Room Bezel = 3 mm Lower Brightness, Resolution and Life

5 Video Source Front Screen Side Structure 1.5 mm Black Frame 1.5 mm Black Frame Central Light DLP Projector Black Bezel of DLP at about 3 mm

6 PDP Three-Cells to Trip-Color Three Vacuum Cells Displayed as Trip-Color Vacuum Cells is keeping Discharged and easily to cause Cell Burned Vacuum Cells is keeping Discharged and easily to cause Cell Burned Front Glass Fluorescent Address Electrode Discharge UV General Electrode

7 Real Picture of PDP Vacuum Cell Pixel Pitch 1.3 mm 3 Vacuum Cells Displays as one Pixel 3 Vacuum Cells Displays as one Pixel Cell Dimension is physically limited to be smaller - Resolution is lower Cell Dimension is physically limited to be smaller - Resolution is lower 1.3 mm Power Consumption is about 760 w/m 2 Power Consumption is about 760 w/m 2

8 PDP Video Wall Bezel at 3 mm

9 LED Video Wall LED Background LED Floor Ballet Actress Audience

10 LED Display LED Display is a Matrix of R,G,B LED 6 ~ 20 mm A Nice Watching Distance LED Pitch x 3,000 P20: 60 m Watching P6: 18 m Watching

11 0.02° If LED Pitch = 20 A nice Watching Distance 20 x 3,000 mm 60 meters If LED Pitch = 20 A nice Watching Distance 20 x 3,000 mm 60 meters Eyes Resolution Ratio 0.005° Thats why we still can detect the brightness and darkness between LED dots even over 60 meters away Thats why we still can detect the brightness and darkness between LED dots even over 60 meters away 20 mm Relationship between LED Pitch and Eyes Resolution Ratio

12 LED Dots Detected by Long-Focus LED Dots are clearly detected when a Long-Focus camera focuses on actors who are just before the LED screen LED Dots are clearly detected when a Long-Focus camera focuses on actors who are just before the LED screen And some dots damaged

13 Video Wall over 30 Years DLP (Projector) Thicker Body Lower Brightness and Resolution PDP (Plasma) Lower Resolution Higher Power Consumption and Heat Generation PDP (Plasma) Lower Resolution Higher Power Consumption and Heat Generation Why they dominated Video Wall market over 30 years? LED is good for outdoor Long distance view wider pitch with lower price Pitch of LED now reaches 1.9 mm a precondition of indoor display The major reason is they have a small Bezel at about 2~3 mm Pitch pieces LED per meter 277,000 LED per m 2 Its a really challenge at Unit Price, Power Consumption and Heat Generation

14 LCD uses Leaser Cutting Tech., a maturity process to build higher resolution - A mobile can easily reaches Full HD at 2K - A size of 4 mobiles reaches 4K LCD uses Leaser Cutting Tech., a maturity process to build higher resolution - A mobile can easily reaches Full HD at 2K - A size of 4 mobiles reaches 4K Why Video Wall is not LCD Yesterday Why LCD only came to Video Wall applications in years of 2010? Obstacle is the Black and Dead Bezel which is a nature of LCD Black and Dead Bezel is a Bar jails LCD for Video Wall applications Black Bezel over Full HD display likes one tights his belt over his suit Black and Dead Bezel is a Bar jails LCD for Video Wall applications Black Bezel over Full HD display likes one tights his belt over his suit Its an obstacle for some applications sensitive to Black and Dead Bezel -Display an import person like TV Station -Showing data in Central Bank -Detect dots of carriers on map or radar in control room Its an obstacle for some applications sensitive to Black and Dead Bezel -Display an import person like TV Station -Showing data in Central Bank -Detect dots of carriers on map or radar in control room

16 Civil TV in Supermarket Industry Super Narrow Frame > LCD Display Result Civil TV is no way for Video Wall DLP and PDP Is estimable for Narrow Bezels DLP and PDP Is estimable for Narrow Bezels The Narrower the Bezel, the Higher the Technology But No Dead Bezel, No Active LCD! Where is a solution? But No Dead Bezel, No Active LCD! Where is a solution?

17 Its a fault to display everything! (Face Destroyed, Eyes and Nose are gapped) Its a fault to display everything! (Face Destroyed, Eyes and Nose are gapped) Image under Bezel must be cut / covered (Displaying Lost) Image under Bezel must be cut / covered (Displaying Lost) Displaying Lost under Super Narrow Frame Whatever narrow of the bezel video under the bezel must be cut / covered What wrong with this picture?

20 Transparent Frame (Active Bezel) Transparent Frame (Active Bezel) Transparent Frame (Active Bezel) Super Narrow Frame (Dead Bezel) Super Narrow Frame (Dead Bezel) Transparent Frame (Active Bezel) Restores the Display Cut / Covered by Dead Bezel Transparent Frame (Active Bezel) Restores the Display Cut / Covered by Dead Bezel

21 PIP on Transparent Frame Transparent Frame (Active Bezel)

22 Conclusion LCD is the King of Display Every one takes several LCDs and LCD spreads everywhere LCD is the King of Display Every one takes several LCDs and LCD spreads everywhere LCD for video wall is only about three years but almost kills Thirty-years DLP and PDP LCD for video wall is only about three years but almost kills Thirty-years DLP and PDP Transparent Frame (Active Bezel) is assisting LCD to be the King of Video Wall Transparent Frame (Active Bezel) is assisting LCD to be the King of Video Wall
