Philips developed a simple bi-directional 2-wire bus for efficient inter-IC control. This bus is called the inter IC or I²C-bus. At present, Philips’ IC range includes more than 150 CMOS and bipolar I²C-bus compatible types for performing functions in all three of the previously mentioned categories. All I²C-bus compatible devices incorporate an on-chip interface which allows them to communicate directly with each other via the I²C-bus. This design concept solves the many interfacing problems encountered when designing digital control circuits.

The global lighting-industry leadership of OSRAM Opto has transformed how information is displayed through the use of proprietary Pictiva™ OLED technology. Pictiva™ displays offer vivid color and contrast, video capability, wide viewing angle, and a thin-form factor to enable developers and engineers more design flexibility.

A touch screen interface can be added to Pictiva™ 2.7 inch or similar OLED displays to enhance its’ operation. This application note shows how the hardware and software can add a touch function to an existing OLED display.

This application note demonstrates the use of ambient light sensor with OLED under a wide range of illumination conditions from a dark environment to direct sunlight.

OLED Display Module Handling and Care

OLED displays are similar to Plasma or CRT’s in that they have a tendency to burn-in an image that is stationary on the display screen. A screen saver application is highly recommended in order to reduce burn-in effects that may be seen on OLED displays.

The purpose of this application note is to provide the reader with a better understanding of the physical properties of a 36 mux rate OLED display and demonstrate different basic register settings for the OLED driver to optimize driving conditions in order to achieve the highest quality display and maximize its lifetime.

This application note describes three different communication protocols between MCU and an OLED driver.

There are many different graphics file formats that can be created using various imaging programs, such as .bmp, .jpg, .gif, .tif, etc. However, understanding the internal structure of each image file format is necessary when manipulating and downloading images to OSRAM OLED display.

The objectives of this application note are to explain the fundamental concepts of the internal structure of a 24-bit, uncompressed bitmap file and provide instructions on how to convert a bitmap file from 24-bit to 4-bit that still retains its highest resolution possible along with the C/C++ source code.

OLED technology is an emissive technology. This means that unlike LCDs, power consumption is not a fixed value; it varies with image content. The driving of an LCD with changing images consumes little power because there is almost no current flow in the LCD cell. The main contributor to LCD power consumption is the backlight which always illuminates the whole viewing area. For an OLED, this is comparable to an All-Pixels-ON scenario, but this image conveys no information. Therefore, an OLED with a typical image that consists of ON and OFF pixels has lower power consumption because the dark OFF pixels consume negligible power.

OSRAM OLED Product Development is taking another step to demonstrate graphics images on OSRAM Pictiva™ OLED displays. Graphics images use lines and shapes to form graphical objects geometrically, such as Line, Circle, Arc, Square, text, or together combine these objects to create sophisticated graphical drawings.

This application note mainly focuses on the generation of images, icons, and text. Although the algorithms and features used to construct graphics objects require a fundamental understanding of mathematics and engineering, with the aid of this software reference manual, designers can quickly utilize our Graphics Generation software as a library reference to have a basic understanding of what is needed to draw and display text or graphics objects on Pictiva™ OLED displays.
