Abstract: A contact image sensor module for scanning the image of a planar object comprises a white organic electroluminescent device, a plurality of cylindrical lenses, a color filter, and a contact image-sensing element. The white organic electroluminescent device emits white light which illuminates the planar object to result in reflected light. The cylindrical lenses direct the reflected light to the color filter, and the filtered light forms an image in the contact image-sensing element.

Abstract: An organic light-emitting device (OLED) with a heat dissipation structure includes a substrate, an anode layer, a metal layer, a light-emitting layer, a cathode layer, at least one external anode, and at least one external cathode, wherein at least one external anode is connected to the anode layer, and at least one external cathode is connected to the cathode layer. The metal layer, due to having a high thermal conductivity, conducts the heat generated during the operation of the light-emitting layer to the external anode. The cathode layer, due to having a good thermal conductivity, also conducts the heat generated during the operation of the light-emitting layer to the external cathode. In addition, the tips of the metal layer after being etched may cause discontinuity of the coating layer of the light-emitting layer and abnormal light emission.
