Embodiment Construction

[0039] Hereinafter, the embodiments will be described in detail as a reference of the present invention, and the examples are accompanied by illustrations. In the illustrations or descriptions, the same reference numerals are used for similar or identical parts. In the illustrations, the shape or thickness of the embodiments may be exaggerated to simplify or facilitate labeling. Parts of the elements in the drawings will be described in the description. It is to be understood that elements not shown or described may have various forms known to those skilled in the art. In addition, when it is described that a layer is on a substrate or another layer, the layer may be directly on the substrate or another layer, or there may be an intermediate layer therebetween.

[0040] In the description, the descriptions of "on the substrate" (overlying the substrate), "on the layer" (above the layer) or "on the film" (on the film) etc. indicate the relative positional relationship with th...

Abstract

Organic electroluminescent devices are disclosed. A representative device incorporates a substrate that comprises a control area and a sensitive area. A switch device and a driving device are disposed overlying the control area. A photo sensor is disposed overlying the sensitive area. An OLED element is disposed in the sensitive area and illuminating to the photo sensor. A capacitor is coupled to the photo sensor and the driving device, wherein a photo current corresponding to the brightness of the OLED element is generated in the photo sensor responsive to the OLED element illuminating the photo sensor such that a voltage of the capacitor is adjusted by the photo current to control the current passing through the driving device, thus changing the illumination of the OLED element.

Description

technical field [0001] The invention relates to a display element, in particular to an organic electroluminescence display element and a manufacturing method thereof. Background technique [0002] Organic electroluminescent devices (also known as organic light emitting diode (OLED) displays) emit light based on organic molecular materials (which can be divided into small molecule materials according to molecular weight) And polymer material (polymer material)) apply an external electric field to make it produce luminescence. Organic electroluminescent devices (organic electroluminescent devices) are self-luminous (self emission) components, dot matrix type display (dot matrix type display), with light and thin, high contrast, low power consumption, high resolution, short response time (fast response time), no need for backlight and wide viewing angle, and its panel size can be from 4mm microdisplay to 100mm large outdoor signage display, which is regarded as the next genera...
