Samsung patents screen with extra clear sub-pixel for brighter displays
Samsung describes a display design that adds a fourth, transparent sub-pixel to the standard red, green, and blue setup. This extra section uses a clear filter instead of a colored one, allowing more light from the backlight to pass through the screen.
In the filing’s own words
A display apparatus including: a backlight unit including a red LED, a green LED, and a blue LED; and a liquid crystal (LC) panel configured to transmit therethrough light emitted from the backlight unit, wherein the LC panel includes: a LC layer including independently controllable LC cells; a color filter layer on the LC layer and including a red filter, a green filter, a blue filter, and a transparent region; and one or more pixels, each of the one or more pixels including: a first sub-pixel including the red filter and a first LC cell of the LC cells; a second sub-pixel including the green filter and a second LC cell of the LC cells; a third sub-pixel including the blue filter and a third LC cell of the LC cells; and a fourth sub-pixel including the transparent region and a fourth LC cell of the LC cells.
What exactly they claim (claim 1)
1. A display apparatus, comprising: a backlight unit comprising a red light-emitting diode (LED), a green LED, and a blue LED; and a liquid crystal panel configured to transmit therethrough light emitted from the backlight unit, wherein the liquid crystal panel comprises: a liquid crystal layer comprising liquid crystal cells which are configured to be independently controlled; a color filter layer on the liquid crystal layer and comprising a red filter, a green filter, a blue filter, and a transparent region; and one or more pixels, each of the one or more pixels comprising: a first sub-pixel comprising the red filter and a first liquid crystal cell of the liquid crystal cells; a second sub-pixel comprising the green filter and a second liquid crystal cell of the liquid crystal cells; a third sub-pixel comprising the blue filter and a third liquid crystal cell of the liquid crystal cells; and a fourth sub-pixel comprising the transparent region and a fourth liquid crystal cell of the liquid crystal cells.
