Abstract text

In an active matrix organic light emitting diode (AMOLED) display panel having an improved OLED circuit layout in the TFT back panel, the AMOLED pixels in the AMOLED pixel array are arranged to have the TFT circuit portions of the AMOLED pixels in clustered regions so that each pulse of laser beam during laser annealing of the amorphous silicon film irradiates mostly TFT circuit portions, thus, allowing more efficient laser annealing process.
