Floating-point pixel values

Abstract

A floating-point display includes pixels. Each pixel can have a pixel memory for storing a pixel value, a light emitter, and a pixel circuit operable to control the light emitter to emit light corresponding to the pixel value. Each pixel value comprises a floating-point value that can be a binary value with a mantissa of M bits and an exponent of E bits. The pixel circuit can output a pulse-width modulation signal of M+E bits to control the light emitter to emit light by sequentially outputting bits of the mantissa in correspondence to the periods of the pulse-width modulation signal shifted in response to the value of the exponent. Different values of the floating-point pixel value can be unique and monotonic, can comprise multiple linear functions, and can increase from zero.
