摘要： With a double-sided display module having a main panel and a sub-panel sharing drive signals, the image quality of the main panel is improved. When the display devices uses the same driver IC to drive the main panel and the sub-panel, the contrast is uneven at the border area between a region of the main panel where signal electrodes share drive signals with the sub-panel and a region of the main panel where signals electrodes do not share drive signals. In order to make the contrast unevenness practically invisible to the naked eye, an unshared electrode adjacent to the border between different contrast levels on the main panel is connected to the dummy electrode. The dummy electrode has to be smaller than the total overlap area of one electrode that constitutes a pixel of the sub-panel. In the case where the sub-panel has more than one dummy electrode, the dummy electrodes are gradually made smaller.

摘要： An optical transmission device obtains driving control data corresponding to a temperature detected by a temperature detection circuit (112) from memory means (173), controls a driving current to be supplied to a laser diode (100) based on the driving control data, and measures a driving current to be actually supplied to the laser diode whose emission power is held constant by an automatic optical output control circuit (115, 113). Further, when the difference between the measured driving current and a driving current determined by the driving control data corresponding to the detected temperature at that time exceeds an allowable range, the optical transmission device updates the driving control data. Upon determination of the deterioration of the laser diode, the progress of the deterioration of the laser diode is determined based on the difference between a driving current defined by driving control data corresponding to a newly measured temperature and an actual driving current formed by automatic optical output control. Therefore, a distinction between whether an increase in driving current due to the automatic optical output control results from the deterioration of the laser diode and whether it results from a variation in ambient temperature is reliably made.
