MIPI Stands For Mobile Industry Processor Interface. The MIPI was created in 2003 by ARM, Alliance formed by TI, The purpose is to bring up the various interfaces inside the phone (camera CSI, display screen DSI, RF / baseband interface, DigRF, etc.) Standardization.Thus reducing the complexity of mobile phone design and increasing the design flexibility, Currently, the more mature interface applications have DSI (display interface), And the CSI (camera interface), Both have a relatively complex protocol structure.

What is SPI ? SPI is short for Serial Peripheral interface and, as the name suggests, a serial peripheral interface. Motorola was first defined on its MC68HCXX-series processors.

Compared with VR applications, AR (Augmented Reality) displays require high brightness and contrast. More OLED (organic LED)  Through an ingenious combination of enhancements, the SONY Semiconductor solution increases the brightness of the Micro OLED screen by three times while maintaining the same service life

RT4723 is a Dual output AMOLED Power IC with integrated boost converter for Vpos and charge pump for Vneg in small CSP-15B 1 39x2 07 package, ideal for 1 inch to 2 inch panels in battery-powered wearable portable applications Extremely small PCB footprint.

The 7-inch TFT color screen is an indispensable component of many intelligent products in the information age. As an intelligent terminal, we all hope that the 7-inch TFT color screen we purchase is able to deliver good quality, high yield, and good product reliability, as this is required to ensure the stability of the whole machine.

Tandem OLED is a highly efficiency OLED structure that combines multiple conventional OLED devices with connected layers. Each traditional OLED module has its own complete functional layer, including the hole/electron injection layer, the hole/electron transport layer, and the light layer. Because all OLED modules share one anode and one cathode, less raw materials are required.

TFT displays are a common type of display, and because of its characteristics we may have some abnormalities in the production process and use, such as the TFT display becoming yellow. This unfortunate phenomenon is very common, so today Panox Display will analyze the reasons for TFT

Brief steps of driving LCD, usual problems developers met in driving LCD, how to power the backlight of LCD.

The OLED display is characterized by self-luminescence, high contrast, low power consumption, lightweight, thin thickness, etc. It is called the next generation of display technology. According to the drive mode, OLED can be divided into active drive (AMOLED) and passive drive (PMOLED). So what are the differences between PMOLED and AMOLED? 

When developers try to drive the LCD or OLED panels, there are many pins to interface, so what do these pin assignments mean?

MPU interface mode: Display data written to DDRAM, often used for still picture display. RGB interface mode: Display data does not write to DDRAM, is directly written into the screen, is fast, and is often used to display video or animation.

Raspberry Pi is a small computer that can be used for a variety of projects. Learn how to drive LCD with Raspberry Pi and HDMI controller board.

Now let's introduce the structure and display theory of TFT-LCD. To drive an LCD module, it`s necessary to have a systematic understanding of its structure. 

1. LCD type, Circuit connection, Display principle. 2. LCD Controller REGBANK Register Group. 3. LCD Color Palette. 4. Write The Driver Program. 5. 5. Compilation And Testing. 6. Modifying the kernel

Reducing power dissipation is important for the mobile device which is supplied by batteries.

Use the ARM7 board to drive the  2.8 inch OLED, including the code.

Some precautions in using OLED Modules, contains clearing, power off, storage, temp....

This article will take you through how to write a driver for an OLED display. Here I am using hardware IIC from HAL library and OLED screen from SSD1306.
