  • General Features:
  • The prototype is a 46-inch LCD with Dolby’s HDR LED backlight technology
  • LCD panel provides a resolution of 1920 x 1080 pixels (Full HD), fitting a native 16:9 aspect ratio
  • Brightness: greater than 4,000 cd/m2
  • Contrast ratio: INFINITE! Full On / Full Off
  • Step size: 16 bits of luminance
  • Luminance uniformity: more than 95% through the LCD panel
  • Prototype Detailed Technical data:
  • 1,838 LEDs
  • Each LED is powered by 500 mA and provides a luminous flux of 80 lm
  • The LED drivers are Texas Instruments TLC5940
  • Each driver has 16 outputs grouped in parallel 4 by 4
  • Each driver feeds 4 LEDs
  • LED brightness is controlled by PWM (with up to 12 bit grey scale resolution)
  • The BLU boards are connected to the HDR processing board trough an LDVS interface
  • The color resolution of the LCD panel is 8/bit color
  • The HDR algorithm expands the signal from the source in 16/bit color
  • A stream of 8 bit are sent to the LCD panel and the others 8 bit are sent to the BLU
  • The total effect between the LCD and BLU is equivalent to 16 bit wide dynamic range display

Ενδιαφέρον κομμάτι τεχνολογικά και μόνο, αλλά δεν μπορώ να καταλάβω προς τι η τόση φωτεινότητα.

Αυτη ειναι η max φωτεινοτητα προφανως.

Ναι εννοείται πως είναι η max απλά και πάλι το νούμερο είναι αρκετές φορές μεγαλύτερο από την max των σημερινών LCD, οι οποίες είναι ήδη περισσότερο φωτεινές από όσο είναι αναγκαίο. Άσε που αντιστοιχεί και σε κατανάλωση 2000W περίπου.
