Device Structure of OLED Module

The typical device structure of OLEDS is a laminated anode (transparent electrode), a hole injection layer, a hole transport layer, an emitting layer, an electron transport layer, an electron injection layer and a cathode (metal electrode) on the glass substrate. Each layer is stacked on the glass substrate using vacuum deposition technology. Because organic materials are affected by oxygen and moisture,lcd panel of  OLEDs are encapsulated by sealing materials such as metal or glass after being produced into layers on the glass substrate.

Working Principle of OLED

Tsingtek OLED Display Module has a simple structure, which has an organic light emitting layer between anodes and cathodes. When a lcd module direct current is applied to the device, holes with positive charges are injected from anodes and electrons with negative charges are injected from cathodes into the organic light emitting layer. Then, the organic molecules emit light when the positive hole and the negative electron couple and generate energy in the organic light emitting layer. Because most of the organic materials are insulators and do not easily conduct current, organic light emitting layers need to have very thin structures, approximately 0.1um.

OLED is Short for organic light-emitting diode

OLED is Short for organic light-emitting diode, a OLED Display Module device that sandwiches carbon-based films between two charged electrodes, one a metallic cathode and one a transparent anode, usually being glass. The organic films consist of a hole-injection layer, a hole-transport layer, an emissive layer and an electron-transport layer. When voltage is applied to the OLED cell, the injected positive and negative charges recombine in the emissive layer and create electro luminescent light. Unlike LCDs, which require backlighting, OLED displays are emissive devices - they emit light rather than modulate transmitted or reflected light.

The maximum resolution of computer monitors

The easiest convention is the one that’s used to describe the maximum resolution of computer monitors. A lot of TFT LCD displays have a maximum resolution of 1280×800, and the resolution of larger computer screens often go into the neighborhood of 1680×1050. These numbers describe the width and height of the display in pixels –the building blocks of your display. Some displays have different pixel densities (most famously, Apple’s retina displays), meaning the physical size of two displays with the same maximum lcd graphic display resolution is not necessarily uniform. But the actual resolution (that is, the amount of available building blocks to construct a picture) is unambiguous.

OLED panels are emissive

Graphic oled panels are emissive so they do not require a separate backlight like LCD technology does. The elimination of the backlight helps reduce the OLED display's overall power consumption when compared to LCDs. The OLEDS also does not suffer from loss of contrast due to bleed through of the backlight in the "off" pixels. OLEDs, being emissive, have a consistent contrast ratio greater than 100:1 with no limitation in viewing angle.

Graphic Display business

LCD Graphic Display resolutions can be a rather cryptic business, with multiple standards used to describe the same display resolution in 10 different ways. All of those technical terms tend to change based on the display’s purpose (television versus computer monitor) and even your region . The difference between full HD and HD Ready and even how Apple’s retina display works. Today, we’ll help you make sense of the different terms people tend to throw around when describing display resolutions. When buying a computer monitor or a TV screen, it can be incredibly useful to know what those numbers mean. Not just to differentiate between two QVGA lcd displays, but also to determine what kind of display you should be looking for.

An LCD consists of many components

A typical LCD uses a cold-cathode fluorescent tube or multiple lcd modules. Two types of custom lcd display are used: (1) that which emits short wavelength emission, which is converted to longer wavelengths by means of a fluorescent material (downconversion) and (2) that which emits the three color primaries . Thus the light source for an LCD is either linear or point, so the light must be converted to the area form to be used as a backlight unit. The light reflected by the reflector passes through the light guide and is diffused. A light guide is made of high refractive index material, such as an acrylic polymer, which delivers the light by total internal reflection due to the refractive index difference between it and the surrounding air. The light guide structure is designed such that uniform luminance distribution across the area of the display can be achieved.
