    • Embodiments of a transistor capable of outputting uniform driving current despite deviations in manufacturing processes, and an organic light emitting diode display (OLED) capable of displaying high picture quality by employing the transistor are disclosed. The transistor comprises a semiconductor layer formed on a substrate and including a source connected to a source electrode through first and second contacts, a drain connected to a drain electrode through third and fourth contacts, a channel formed between the source and the drain. The transistor further comprises a gate aligned with the channel with a gate insulating layer interposed between the gate and the channel. The first to fourth contacts are formed along different parallel axes which are perpendicular to a direction along which a laser beam proceeds during transistor manufacture.

    • The present invention relates to an apparatus and method for controlling a lamp in a refrigerator, wherein a time period when the refrigerator lamp is turned on is added up while the lamp is repeatedly turned on and off at least once, and the lamp is temporarily turned off when the added time period reaches a predetermined time period value, so that the lamp can be prevented from being overheated and parts positioned adjacent thereto from being thus deformed due to heat generated from the lamp. The method of the present invention comprises (a) calculating a time interval from a point of time when an refrigerator door is closed and the lamp is thus turned off to a point of time when the door is opened again, (b) determining whether the calculated time interval exceeds a predetermined time interval value, and (c) controlling temporarily turning off the lamp when it is determined in step (b) that the calculated time interval does not exceed the predetermined time interval value and simultaneously an accumulative sum of the time period when the lamp is turned on exceeds a predetermined accumulative sum value. Therefore, according to the present invention, there is an advantage in that a time period for cooling heat generated near the lamp can be provided such that the deformation of injection molded parts near the lamp and the fire hazard due to the heat generated from the lamp can be prevented. Further, there is another advantage in that unnecessary consumption of electric power due to frequent opening/closing of the refrigerator door can be reduced.
    • 本发明涉及一种用于控制冰箱中的灯的装置和方法,其中当灯反复打开和关闭至少一次时,将冰箱灯打开的时间段相加,并且灯暂时转动 当添加的时间段达到预定的时间周期值时,可以防止灯被过热,并且与其相邻的部件因由灯产生的热量而变形。 本发明的方法包括:(a)从关闭冰箱门并将灯关闭的时间点再次打开到门的时间点计算时间间隔,(b)确定是否 计算时间间隔超过预定时间间隔值,以及(c)当在步骤(b)中确定计算出的时间间隔不超过预定时间间隔值并且同时累加时间的总和时,控制暂时关闭灯泡 当灯开启时的周期超过预定的累积和值。 因此,根据本发明的优点在于,可以设置用于在灯附近产生的冷却热的时间段,使得灯附近的注射成型部件的变形和由于灯产生的热量引起的火灾危险 可以防止。 此外,还有另一个优点是可以减少由于冰箱门的频繁打开/关闭导致的不必要的电力消耗。
