CPC G09G 3/32 (2013.01) [G09G 3/2011 (2013.01); G09G 3/2014 (2013.01); G09G 2300/0842 (2013.01); G09G 2310/0221 (2013.01); G09G 2310/0251 (2013.01)] | 19 Claims |
1. A display device, comprising:
a plurality of pixels arranged in an array with rows and columns,
a plurality of column lines, each connected to the pixels of one of the columns,
a plurality of row lines, each connected to the pixels of one of the rows, and
a control unit coupled to the plurality of column lines and configured to generate a column pulse for a selected column line of the plurality of column lines, and connected to the plurality of row lines and configured to generate a data signal for a selected row line from the plurality of row lines,
wherein the data signal comprises a set pulse which, when the pixel is set to a radiating state, is applied to the pixel connected to the selected column and row line at least in a portion when the column pulse is applied to the pixel, and drives the pixel such that a light emission of the pixel depends on the time offset between the column pulse and the set pulse,
wherein the plurality of pixels each comprise a light emitting semiconductor device and a pixel controller, and
wherein the pixel controller comprises a charge storage for the energy of the set pulse, the charge amount of the charge storage being limited by a protection diode or circuitry in parallel with the charge storage.
