How Does a Thin Film Transistor Television Screen Address Each of The Picture's Pixel Points to Color It?
I'm interested in LEDs and Active Matrix TFT (thin-film-transistor) the color resolution/reproduction from devices such as portable video devices when compared with larger ones, like the jumbotrons in football stadiums, signs and venues such as the Fremont Street Experience in Las Vegas, NV.
The hedge [of hawthorns] formed a type of suite of chapels disappearing under the wall of their flowers heaped as on an altar; under them, the sun placed on the ground a grid of light, as if it had come through a glass window; their fragrance was as smooth and as clearly defined in its form as if I had stood before the Virgin’s altar, and the flowers, so ornamented, each distractedly held its dazzling bouquet of stamens, fine and shining ribs of flamboyant style like those which in the church line the ramp of the rood-screen or the mullions of stained-glass windows and which bloomed into the white flesh of strawberry blossoms.
—Marcel Proust (1871–1922)
My direct interest is in applying a combination of the type of addressing methods currently in use on LED signs such as those used in major cities and the methods used in handheld devices. I welcome suggestions and input on which form of addressing the various LED groups would best work in a football-field-sized, "justified motion field" a grid that acts as a large video screen projecting from below the field, (via fiber optics), while built-in sensors underneath interact with Active RFID (Radio Frequency Identification tags, (using something akin to Wi-Fi or Bluetooth Technology), for signal ID verification of movement above the field, tracking movements of ball/players and half-time shows. amkhali,
I'm sure you think that you know what you're talking about, however, your answer applies to a whole different method of picture production, one which utilizes an electron gun and would apply to Cathode Ray Tube CRT Televisions and not the kind I am inquiring about: portable thin film transistor type of LCD Liquid Crystal Displays in small handheld devices, these use a wire-grid addressing method that specifies a signal to a point on a grid from both sides and top to bottom to tell each pixel at each point of intersection on the grid to light up a specific color, red, blue, green or shades and combinations of the three to form 16,000,000 colors or, all at once to form white and none on at all at that grid point to form a dead cell pixel, many of which, when 'off' make shades and spots of gray to black. There is no electron gun involved, as the only backlighting provided is via 2 or 4 side lights, usually flourescent strip bulbs. I need replies from persons in such fields.
