DISPLAY DEVICE HAVING DIGITAL AND ANALOG SUBPIXELS
An organic EL display including a plurality of digital data lines; a plurality of analog data lines; a plurality of pixels arranged in a matrix, each pixel having a digital sub-pixel connected to one of the plurality of digital data lines and an analog sub-pixel connected to one of the plurality of analog data lines; and a plurality of hybrid data drivers, each connected to the respective digital data line and the respective analog data line, for receiving input data, dividing the input data into digital data and analog data, and supplying digital data to the respective digital data line and analog data to the respective analog data line
1 . An organic EL display comprising:
(a) a plurality of digital data lines;
(b) a plurality of analog data lines;
(c) a plurality of pixels arranged in a matrix, each pixel having a digital sub-pixel connected to one of the plurality of digital data lines and an analog sub-pixel connected to one of the plurality of analog data lines; and
(d) a plurality of hybrid data drivers, each connected to the respective digital data line and the respective analog data line, for receiving input data, dividing the input data into digital data and analog data, and supplying digital data to the respective digital data line and analog data to the respective analog data line.
2 . The organic EL display of claim 1 , wherein each digital sub-pixel includes a static memory for storing the digital data supplied from the connected digital data line.
3 . The organic EL display of claim 1 , wherein the matrix comprises one or more columns of digital sub-pixels and one or more columns of analog sub-pixels, and wherein each digital data line is provided along a respective column of digital sub-pixels, and each analog data line is provided along a respective column of analog sub-pixels.
4 . The organic EL display of claim 1 , wherein the hybrid data driver comprises an output register for storing the input data, and a digital processor and an analog processor for processing the input data stored in the output register.
5 . The organic EL display of claim 4 , wherein the input data is supplied to the output register via a data register, and the data register sequentially supplies the input data for the digital pixel and the input data for the analog pixel to the output register.
6 . The organic EL display of claim 1 , wherein the input data is digital data having at least one upper bit and at least one lower bit, and wherein each hybrid data driver divides the respective input data by selecting one or more upper bits of input data to be the digital data and by selecting one or more lower bits of input data to be analog data.
7 . An organic EL unit pixel comprising a digital sub-pixel and an analog sub-pixel.
