Graphical LCD display interface control

Tsingtek LCD Graphic display module helps the user to gain invaluable practical experience of the principles and application of Graphic LCD display in Microcontroller based projects. The object is to connect and program a Microcontroller to display data, images and monitoring. Graphical display module is generally used in the applications such as temperature monitoring, Industrial automation, outdoor moving sign, video wall and many more. We give a contrast control and backlight control on the module.

TFT LCD Display Interface : SPI

This TFT LCD Display breakout board is the best way to add a colorful and bright display to any application/project. Since the display uses 4-wire SPI to communicate and has its own pixel-addressable frame buffer, it can be used with every kind of microcontroller with SPI lcd communication protocol.The TFT display is 3.2" wide and has 320x240 color pixels. The TFT driver (ILI9341) can display full 6-6-6 (R-G-B) and is configurable. The example code uses 5-6-5 (R-G-B).
The display comes with the connectivity board that can be interfaced to the target controller through a 14 pin, 2.54mm flat cable. The unit can be used as an external interface display card for various applications.

An OLED Module work in microcontrollers systems

An OLED Module that allows microcontrollers systems like the PICAXE to display messages and images on a 128x32 oled display (white on blue GLCD included). Interface via one serial line. Self assembly kit. Optional software also available to enable download of graphics into the modules EEPROM memory. The module is a compact, handheld spectrometer. It uses DLP technology to focus the light reflected off a sample to a single, low-cost sensor, offering a cost-effective alternative to the more complicated linear array-based detector designs found on larger, more expensive devices. It could be utilized in a handheld spectrometer for mobile lab measurements. The demo application was able to detect the type of chocolate when the chocolate was placed on the sensor by checking sugar content.

Graphical LCD Module with RGB Interface

Offered as a display option for the Tower System, the Graphic LCD module brings graphical display to your designs and includes RGB interfacing. Mounted on the secondary elevator module, this peripheral module lets you see your designs come to life on a 4.3" QVGA lcd display panel. It is easily paired with controller modules featuring an integrated LCD display controller, such as the Graphic LCD MCU module, and a number of peripheral modules for a robust, modular prototyping system that can be customized to your design needs.

Differences between OLED, LED, LCD, and TFT Screens

LCD display: liquid crystal display. Works by adjusting the amount of light blocked. Usually has a backlight but might not . The green-black ones can be very cheap and are a mature technology. Response time can be slow.
TFT LCD displays :is a type of LCD with a thin film transistor attached to each pixel. All computer LCD screens are TFT since early 2000s; older ones had slower response times and poorer colour. Cost is now very good; power consumption is fairly good but dominated by the backlight. Has to be manufactured out of glass.
LED display: light emitting diode. As the name suggests, emits light rather than blocking it like LCD. Used for red/green/blue/white indicator lights everywhere. Some manufacturers advertise "LED" displays that are TFT screens with a white LED backlight, which is just confusing. Ones that are real LED screens are usually OLED.
OLED Display: organic LED (rather than silicon or germanium based like regular LEDs). Comparatively recent technology, so cost still quite variable and not available in really large sizes. In theory can be printed on plastic, resulting in lighter flexible displays with good brightness, good power consumption and good response time.

Tsingtek character oleds have the potential to be cost effective

Tsingtek character oleds have the potential to be cost effective. They have fewer processing steps and are also less materials and equipment intensive than today’s LCDs. As OLED/lcd module manufacturer technologies mature, OLED production yields should continue to improve and larger-scale equipment be brought on line. As a result, production costs will continue to decrease - ultimately enabling OLEDs to outperform LCDs on a cost basis. With so many exciting product capabilities, it’s not surprising that leading market analysts, project that the OLED market will grow rapidly over the next few years. OLED products including a variety of small-area displays for mobile phones and other consumer electronics applications and the introduction of notebook PCs and OLED TVs during the period.

Tsingtek OLED DISPLAYS Superiority

Compared to LCDs, today’s dominant flat panel display technology,Tsingtek OLEDs are capable of providing markedly better performance features. Thinner, lighter and more attractive, OLEDs offer much faster response times, wider viewing angles, higher contrast ratios and brighter, more saturated colors - for a more enjoyable viewing experience. With operating lifetimes now in the tens of thousands of hours, serial oled can also be more energy efficient than LCDs.

How does an ordinary LED/lcd module work?

Before you can understand OLEDs, it helps if you understand how a conventional LED/lcd module works. Take two slabs of semiconductor material (something like silicon or germanium), one slightly rich in electrons (called n-type) and one slightly poor in electrons (if you prefer, that's the same as saying it's rich in "holes" where electrons should be, which is called p-type). Join the n-type and p-type slabs together and, where they meet, you get a kind of neutral, no-man's land forming at the junction where surplus electrons and holes cross over and cancel one another out. Now connect electrical contacts to the two slabs and switch on the power. If you wire the contacts one way, electrons flow across the junction from the rich side to the poor, while holes flow the other way, and a current flows across the junction and through your circuit.
