  • Patent number: 10672329
    Abstract: A light emitting device that achieves long life, and which is capable of performing high duty drive, by suppressing initial light emitting element deterioration is provided. Reverse bias application to an EL element (109) is performed one row at a time by forming a reverse bias electric power source line (112) and a reverse bias TFT (108). Reverse bias application can therefore be performed in synchronous with operations for write-in of an image signal, light emission, erasure, and the like. Reverse bias application therefore becomes possible while maintaining a duty equivalent to that of a conventional driving method.

  • Patent number: 10672675
    Abstract: Related to is a gate on array. A circuit for testing a gate line of an array substrate includes: a test pad and a first switch unit which connects the test pad and the gate line and has an end connected to a control terminal. A voltage is applied to the control terminal to control activation and deactivation of the first switch unit. The gate line is in normal operation when the first switch unit is deactivated, and the test pad tests a signal of the gate line when the first switch unit is activated. In normal display, the first switch unit is deactivated, and the gate line is in normal operation. This can avoid influences of an additional load, which would otherwise cause abnormal display of a picture. In a manufacturing procedure, explosive wound caused by electrostatic discharge of the test pad can be prevented. When a display device cannot be lit, an external voltage can be introduced to activate the first switch unit, so as to detect a signal of the gate line.

    Abstract: An arrangement for a high resolution active matrix display includes organic emissive layers of distinct colors each deposited across continuous regions so as to include more than one pixel emissive region. Color filters are situated to partially block light from at least some of the emissive regions such that primary additive colors are transmitted from distinct subsets of pixels. The emissive layers may be deposited in alternating parallel stripes along rows or columns of the display, or may be oriented perpendicularly with respect to one another such that the emissive layers overlap in the emissive regions of at least some pixels. In some examples, red, green, and blue of pixels are arranged in regular patterns across the display and with the emissive regions for the blue pixels forming a relatively larger area of the display than either the red or green pixels.
