An electronic component specifically created to regulate and drive OLED displays is an OLED display driver IC (Integrated Circuit). OLED displays are light-emitting display panels that are thin, flexible, and flexible when an electric current is applied.
The interface between the display panel and the microcontroller or system driving the display is the OLED display driver IC. It carries out a number of crucial duties, such as:
Power management: The OLED display driver IC controls the power supply to the OLED display, optimising the display’s performance and ensuring efficient power use.
Processing of Incoming Display Data: The IC processes the incoming display data, which may contain graphics, text, or images. It prepares the data for depiction on the screen by converting it into a format compatible with the OLED display.
Control of grey scale: OLED displays are capable of producing a broad spectrum of brightness levels, or greyscale. Smooth transitions and precise portrayal of colours and hues are made possible by the driver IC’s control of the voltage levels provided to the OLED pixels.
Pixel Control: Each OLED pixel functions separately and calls for careful control. In order to enable high-resolution and quick refresh rates, the driver IC controls the activation and deactivation of individual pixels.
Timing Control: To ensure optimal data transfer and display update rates, the IC controls the timing and synchronisation of signals provided to the OLED display. It reduces flickering and ensures a smooth display performance by synchronising the refresh rate of the display with the input data rate.
Interface Communication: The OLED display driver IC supports a number of communication interfaces, including SPI and I2C (Inter-Integrated Circuit). The IC can receive instructions and data from the microcontroller or system in control thanks to these interfaces.
The Global OLED Display Driver IC market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The debut of a touch display driver integration (TDDI) chip for smartphones was announced by OmniVision Group. The brand-new TD4377 TDDI provides a display frame rate of up to 144Hz and 1080-pixel full high-definition (FHD) resolution. Furthermore, compared to LCD screens and touch solutions, its touch sampling rate is twice as fast.
The primary interface between a smartphone’s main chip and the screen is TDDI. TDDI lowers module costs and increases production effectiveness while enabling LCD modules to produce rich and vivid display effects and outstanding touch performance.
Tier 1 manufacturers have utilised OmniVision TD4375 in the mass production of mobile phones. The TD4377 enables improved touch and display performance while consuming less power. TD4377 TDDI samples are now available.
The 28-nanometer (nm) OLED (Organic Light Emitting Diodes) DDIC (Display Driver IC) for smartphone displays has been introduced by MagnaChip Semiconductor Corporation. The most cutting-edge method currently used to make OLED DDICs is the 28nm technology.
The new 28nm OLED DDIC from MagnaChip reduces the form factor by 20% compared to the old 40nm technology, making it suited for smartphones and other mobile devices where small size and thinness are essential characteristics.
MagnaChip also decreased the logic voltage from 1.1V, which was needed for the 40nm products already on the market, to 1.0V, which results in a more than 20% reduction in current voltage consumption and an increase in battery life.
The most recent 28nm OLED DDIC from MagnaChip offers Best-In-Class functionality, power, and price/performance value.
In addition, the 28nm OLED display driver IC is anticipated to reduce EMI (Electromagnetic Interference) levels by 20% compared to current products based on the 40nm architecture, enhancing the call quality of smartphones.
The new 28nm OLED driver IC supports a range of display types, including rigid, flexible, folding, and applications for VR and AR.
For the newest full-screen displays, including bezel-less, hole-type screens, it also maximises design flexibility. At a top smartphone maker, this new display driver has already won its first design-in competition.
