摘要： An electroluminescent (EL) subpixel driven by a digital-drive scheme has a readout transistor driven by a current source when the drive transistor is non-conducting. This produces an emitter-voltage signal from which an aging signal representing the efficiency of the EL emitter can be computed. The aging signal is used to determine the loss in current of the subpixel when active, and an input signal is adjusted to provide increased on-time to compensate for voltage rise and efficiency loss of the EL emitter. Variations due to temperature can also be compensated for.

摘要： Compensation for chromaticity shift of an electroluminescent (EL) emitter having a luminance and a chromaticity that both correspond to current density is performed. Different black, first and second current densities are selected based on a received designated luminance and a selected chromaticity, each current density corresponding to emitted light colorimetrically distinct from the light emitted at the other two current densities. Respective percentages of a selected emission time are calculated for each current density to produce the designated luminance and selected chromaticity. The current densities are provided to the EL emitter for the calculated respective percentages of the emission time so that the integrated light output of the EL emitter during the selected emission time is colorimetrically indistinct from the designated luminance and selected chromaticity.
