摘要： An organic electroluminescent display supplies a reverse bias voltage to an Organic Light-Emitting Diode (OLED) for emitting light. The organic electroluminescent display additionally includes a reverse bias transistor to supply the reverse bias voltage. The reverse bias transistor is connected between an anode of the OLED and a reverse bias power supply, between the anode of the OLED and a first power line supplying a positive source voltage, or between the anode of the OLED and a data line. Furthermore, the reverse bias transistor can be connected between an initialization line and the anode of the OLED. The reverse bias voltage is supplied to the OLED before displaying an image or within a non-display period of a vertical synchronous signal, thereby enabling detection of whether or not the OLED has a defect.

摘要： Powder desiccant is mixed into a seal which adheres a first substrate to a second substrate, thereby sealing a display region. Almost no moisture permeates through the outer surfaces of the substrates sandwiching the display region, while moisture permeating through the seal is adsorbed by the desiccant. An emissive layer is thereby prevented from deterioration due to moisture. By covering the display region with a resin sealing layer composed of resin having desiccant mixed therein, the display region can reliably be protected from moisture. By forming a groove in the substrate and placing a desiccant therein, moisture can be further reliably adsorbed.

摘要： A current control circuit is provided between a power source circuit and a power source line VL which supplies a drive current to an organic EL element provided in each emissive pixel of a display panel. An amount of current flowing from the power source circuit to the power source line VL is detected, and when the amount of current increases, a power source voltage Vdd to be applied to the power source line VL is decreased, thereby decreasing a current flowing thorough the organic EL element. Alternatively, contrast or brightness level of display data to be supplied to each EL element is controlled in accordance with the detected amount of current, so that when the current amount increases, the contrast or brightness level is reduced thereby restricting a current flowing through the organic EL element. Thus, the amount of current flowing through the organic EL element can be restricted to thereby prevent excessive power consumption of the display device.

摘要： There are provided a data register (8) for driving an EL element (6) by a current flowing in a data line (3) via a TFT (5) while sequentially capturing input digital video data for each data line, a latch circuit (10) for holding the data received in the data register (8) during 1 H period, and n analog switches (120 to 123) provided between each data line (3) and a power supply line (11), to which n bit of digital video data for each one data line is input bit by bit as each control signal. The transistors constituting each switch are made different sizes. As the current amount flowing in each switch therefore differs, the EL element emits light with a luminance in accordance with the digital video data.

摘要： An organic EL display device comprises a first TFT (30), which is a switching TFT, an organic EL element driving TFT, and an organic EL element (60) having an anode (61), a cathode (66), and an emissive element layer (65) interposed between both electrodes. The EL element driving TFT comprises a second and third TFTs (35, 40) connected in parallel. Because electrical current to the organic EL element (60) is supplied from a plurality of TFTs (35, 40), variation in the total current value can be suppressed to therefore reduce the variation in luminance, even when characteristics vary among the TFTs driving the organic EL element.
