Abstract: The present invention provides an electrode arrangement for an OLED display. The OLED display is controlled by a driving circuit. The electrode arrangement includes a plurality of first electrodes in a first direction and a plurality of second electrodes in a second direction. The first direction and the second direction are orthogonal. Each of the plurality of first electrodes includes a plurality set of concaves and convexes and two adjacent sets of the plurality sets of the convexes and concaves are engaged with each other. An overlap between the first electrode and the second electrode forms a light-emitting region of the OLED display.

Abstract: An organic electroluminescent device for preventing long distance short comprises an isolated separating layer unit provided on an organic light emitting layer and the two sides of an second electrode, and an isolating trench further provided between a first isolated separating layer and a second isolated separating layer of the isolated separating layer unit. Accordingly, the isolating trench is provided for preventing the irregular electrical contact from the first electrical conducting layer of the top of the first isolated separating layer and the second electrical conducting layer of the top of the second isolated separating layer, that is, the irregularly lighting by the pixels can be prevented from the long distance short for the organic electroluminescent device.

Abstract: A sealing material structure of an organic electroluminescent display panel and a method for manufacturing the same are provided. The sealing material structure comprises a glass substrate, a cover, an adherent layer, and a barrier area. The glass substrate has a light emitting display structure formed thereon and wraps an organic light emitting structure of the light emitting display structure. The cover seals with the glass substrate in an opposite position. The adherent layer is provided between the glass substrate and the cover. The barrier area and/or fillister is grown on the glass substrate and provided at least one side of the adherent layer.

Abstract: An organic electroluminescent device comprises a substrate; a black matrix pattern layer deposited on the substrate as a predetermined pattern; a passivation layer laying over the substrate and the black matrix pattern layer; an anode pattern layer deposited on the passivation as a predetermined pattern; a luminescent layer structure deposited on the anode pattern layer; and an isolation area being an isolation between the anode pattern layer. Among them, the black matrix pattern layer has low reflectivity, and the black matrix pattern layer has a first matrix pattern corresponding to the isolation area or further comprises a second matrix pattern corresponding to the anode pattern layer.

Abstract: An automatic gain control circuit and control method. A variable gain amplifier amplifies a differential input signal. The amplified signal is passed to a filtering circuit for filtering. The amplitude of the filtered output signal is checked using a peak value inspection circuit. The result of inspection is used to set the gain of the variable gain amplifier and further adjust the amplitude of the output signal. The peak value inspection circuit comprises a non-inverted phase differential comparator, an inverted phase differential comparator, an OR gate and a charge/discharge circuit. The output signal is compared with a reference signal through two differential comparators. The result of comparison controls the charge/discharge circuit so that the gain of the variable gain amplifier is varied and the amplitude of the output signal is controlled.
