Transcript: Separation Protection Us/Danger Great Wall of China The Grass is Greener on the other side U.S./Mexican Border A response to a raise in illegal immigration Keeping people out 'who don't belong here' Geographical benifit What we see. What we don't see. They don't pay taxes Sales Tax? They should come here legally Eligibility Requirements based on family or economic need. Visas denied to virtually any poor unskilled, uneducated applicant. Passion What do you consider more important? Life? Land? Human/Human Spending money on other countries. We should focus on the U.S. What about our poor people? We should focus on those who help themselves Stigmatization of welfare Humanity: Sense of humaness; mercy We don't see people as people. Gorey movies Gladiators Public Hangings That we can watch these things. And feel nothing. Illegal Alien Snow Fort Snow Fort Build in Germany in 1961 by East Germany separating the Socialist East, and Capitalist West. Families separated The western condition significantly better, people tried to escape to the other side. Mentality: Where we aren't even allowed to care about people from other countries; We aren't even allowed to care about people within this one who don't provide for themselves. Human Berlin Wall Us/Danger Berlin Wall Us/Them Mentality House The Grass is Greener on the other side Lost our sense of humanity Humanity: the essense of humaness; being human kindness; mercy $5,000- $10,000 How do you feel about illegal immigration? Confliction The Purpose of Walls Walls built as a response to Mexican illegal immigration United States/Mexico Protecting People To Separate Illegal Immigrant The Great Wall of China Time and Cost 3-20 years Purpose of Walls Protection House Built in 1962 Separated capitalist West and socialist East One city separated, separating familes; friends. Western in better condition, people often tried to escape Protecting the border

Transcript: Joyce : Second Presenter * Rely completely upon converting electricity to light * Typically produce only around 200 nits of light *The metallic cathode in an OLED acts as a mirror, with reflectance approaching 80% Problems Faced by OLED Display Circular polarizer Poor Outdoor Performance Poor Color Balance What is OLED? Ways to overcome the problems: WRGB OLED Q & A 1- The plastic, organic layers of an OLED are thinner, lighter and more flexible. 2- OLEDs are brighter than LEDs. 3- OLEDs do not require backlighting like LCDs therefore it consume less power. 4- OLEDs are easier to produce and can be made to larger sizes. 5- OLEDs have large fields of view, about 170 degrees. OLED Structure Thank you for listening :) Related Articles and News Contents : OLED; Disadvantages Ways to overcome the problems: Haida : Preparing the PPT * Organic materials which are used to produce blue color degrades relatively faster than other materials. * Plastic-film stack, combination of quarter-wave retarder and linear polarizer. * Blocks interface reflections generated below the front surface. Sunlight readability, popular with OLEDs and resistive touch. Less Distortion = More Consistent Wide Viewing RGB + WHITE = Greater Color Accuracy Anti-reflection coatings Advantages Reasons: 1- Short lifespan. 2- Expensive manufacture. 3- Can be easily damage by water. 4- Poor outdoor performance. 5- Power consumption 6- Poor color balance * Make OLED with artificial blue tints ~ causes the OLED to look artificial and over saturated. ~ causes a problem called screen burn-in; differences between red, blue and green. * Addition a white layer in RGB is introduced [WRGB] The Future Display Mechanism * Thin-film optical stacks or graded refractive index structure. * Disrupts specular reflection, reducing glare for applications indoors and outdoors. * Sunlight readability. Anti- reflection coatings 1) Role Division 2) Introduction about OLED 3) Advantages and Disadvantages 4) Problems Regarding OLED and Solutions 5) Future Products 6) References 7) Q & A Without coating With coating Circular Polarizer Role Division OLED : Organic Light Emitting Diode OLEDs are solid-state devices composed of thin films of organic molecules that create light with the application of electricity. OLEDs can provide brighter, crisper displays on electronic devices OLEDs use less power than conventional light-emitting diodes (LEDs) or liquid crystal displays (LCDs) used today. Leading to poor readability in bright ambient light, such as outdoors Park Gyu Jin & Kim Jun Tae : Preparing The Report Reason: 120% Color Range; More Natural Hidayah 'Ain: First Presenter ~ Anti-reflection coating ~ Circular polarizer Specifically, RGB OLED uses 3 color pixels; Red, Green and Blue while WRGB OLED uses 4 color pixels including an additional white layer

Transcript: Sam B, Blake, Philip, Brendan Displays Devices What is a display? What is a display? 1 2 3 A device that produces light output from the digital or analog information passed to is by a PC to create an image Displays require their own power source Displays receive data from the PC via a multi-wire cable these connections are often simple, keyed, and color coded 4 Display Types Display Types Analog: Large old bulky TV's Technical term--CRT These use continuous signals (think waves) that vary over time to produce images... Very similar to how sound is sent log distance Digital: Most modern displays LCD LED OLED Plasma Projector These use on/off switching to produce images these displays use exact measurements to produce color and light Having Multiple Displays You can set up a PC in a way that provides the user with multiple monitors these monitors are usually linked together to create a very large Image AMD calls this idea "Eyefinity" Nvidia calls it "Nvidia Surround" Multiple Displays Displays Types There are many ways that light is displayed onto screens. Display Types CRT CRT This is a large and bulky display type called the Cathode Ray Tube. It is a vacuum tube with electron guns and phosphorescent screens to display images. LCD LCD An LCD (Liquid Crystal Display) is a display type for smaller computers. It allows for thinner and sharper displays. They have to have a back-light source and use electrical charges to make the liquid crystals align themselves to pass or block lights. LED Light Emitting Diodes are electronic components that produce light when currents run through in proper directions. They can be combined in large amounts to make massive displays like ones in sport arenas. LED OLED The Organic LED uses organic material to produce light, getting rid of the required back light. OLED More types More types - Plasma uses small cells of charged ionized gas. - Projectors use mirrors or prisms to beam light through lenses to increase size. Modern projectors use Digital Light Processing. Display Connectors 1 2 3 Display Connectors VGA - 3 Rows of 5 pins (DB-15) and usually blue HDMI-3 connectors- Standard, Mini, Micro 4 Display Port-Frowny Face Connector, Like HDMI but one side chamfered, comes in Standard or Mini DP DVI-Digital-Comes in single and dual. Missing 4 pins DVI-Integrated-Full Connector, Digital or Analog, Dual or Single DVI-Analog-Missing Pins Features of a display Properties of a display resolution the number of pixel on a given display first number corresponds to number of columns second number corresponds to number of rows common resolutions: 1920x1080 1600X900 1366x768 resolution Title Native resolution the resoultion that conforms exactly to the number of pixels on the screen A 1920x1080 capable screen has the ability to down scale and appear as a 1600 x 900 display but this would not be it's native resolution Response Time Response Time Response time is a measure of how quickly a pixel can display a change from either black to white or from one shade of gray to another. Lower response time is usually better. Normal response time right now is 1ms for TN panels and 4ms for IPS and VA panels. Refresh Rate Refresh rate the number of times per second the LCD monitor and alter the same pixel represents How many times per second the picture is sent to the monitor common rates are: 60 Hz 120 Hz 240 Hz Brightness Brightness A Display control on the monitor allows you to make the monitor brighter or darker usually represented by a sun icon. In the image to the right, is an example of what a monitor controls icon including how the brightness control looks. Contrast Ratio Contrast Ratio Contrast ratio: the number of shades a monitor can produce between it's brightest white and darkest black Pixel Pitch Pixel Pitch The distance from center of the pixel to the center of another pixel. Pixel pitch typically ranges from .9mm up to 10 if this is too large, it appears as if veiwed through a screen door Filters Filters Privacy: A light altering device that prevents the images from from being seen from most angles, typically used on laptops for public transit etc. Anti-glare: Prevents outside light from hitting the screen and bouncing back (glare)
