Unfortunately, over 83 % of light is blocked by color LCDs when they’re showing white: half because of polarization and at least ⅔ of the rest in each subpixel’s R/G/B color dye. So lots of light is required to get the monitor bright enough… but hey, this “invention” makes it darker than the ambient light. Not taking pixel pitch and TFT corners into account.
There are lots of places where high-res, energy-efficient monochrome backlit or transflexive LCDs with standard inputs (LVDS/eDP/HDMI…) would make sense, such as public transport boards and signage. A mild change in the manufacturing process of standard LCDs (replacing color dyes with the same material but clear) would make such screens, monochrome but with 3x the power efficiency at the same brightness. Now that most light is not blocked, reflectivity would also increase so the display could be visible in daylight with the backlight disabled. Or the customer could opt for a 🟡🟡🔵 pattern if they require the common ⚫🔵🟡⚪ palette at 2x the efficiency.
