A display device including an array of pixels, each pixel including at least three sub-pixels having a LED device emitting light with a blue color point. The first sub-pixel is designed to emit red light having a first color point, the second sub-pixel is designed to emit green light having a second color point, where the LED device of the third sub-pixel is covered with a third wavelength converting layer designed to emit light having a fourth color point. The fourth color point being such that the combination of light emitted by the LED device not converted by the wavelength converting layer and the light converted by the wavelength converting layer results in light having a third color point, where the first, the second and the third color points define a second color space in which a set color space is included.

Display with quantum dot or quantum platelet converter

A method, a digital driving circuit and a LED display where images to be displayed in successive frames are converted from an n-bit digital image to a (m+1)-bit digital image, where m&#x3c;n, by truncating, for each pixel, the (n&#x2212;m) least significant bits or most significant bits of the n-bit digital image, and encoding in the (m+1) bit an indication. Each pixel of the (m+1)-bit digital image is supplied with a first drive current if the (n&#x2212;m) least significant bits are truncated, and each pixel of the (m+1)-bit digital image with a second drive current if the (n&#x2212;m) most significant bits are truncated, where the ratio of the first drive current to the second drive current is such that it results in a brightness ratio of 2{circumflex over (&#x2003;)}(n&#x2212;m), and where the indication provides information on the drive current to be used.
