Techniques for low latency updating of an electrophoretic panel are described. According to such techniques, pixels may be continuously scanned out instead of buffering and updating at fixed scanning slots. In an example, a controller of a device loads, before receiving update data associated with a pixel of an electrophoretic panel, a LUT into a memory accessible to a LUT hardware module. After the LUT is loaded into the memory, the controller receives the update data indicating a color change to the pixel and associates the update data with the LUT. Based at least in part on the update data and the LUT, the controller determines waveform data corresponding to the color change and causes an output on the electrophoretic panel based at least in part on the waveform data.
