A driver IC is an integrated circuit chip that regulates the switching and display of LCD and AMOLED displays. As panel display resolution and data transmission speed grow, so do the needs for driver ICs. The Display Driver IC (DDIC) is one of the panel’s key control components, sometimes known as the brain of the panel.
Its primary job is to provide driving signals and data to the display panel in the form of electrical signals, allowing letters, images, and other image information to be shown on the screen. The Display Driver Integrated Circuit (DDIC)’s primary job is to control the OLED display screen.
It must be compatible with OLED displays in order to be thin, flexible, and foldable, as well as to provide a broad color gamut and high-fidelity display signals. At the same time, OLED consumes less power than LCD to obtain longer battery life.
DDIC sends visual data and operates the display screen with electrical impulses. The placement of DDIC is classified as PMOLED or AMOLED (the distinction between PM and AM is explained further below):
In the case of PMOLED, DDIC feeds current into both the horizontal and vertical ports of the panel, causing the pixel dots to light up. The brightness may be regulated by adjusting the current level.
In the case of AMOLED, each pixel corresponds to a TFT layer (Thin Film Transistor) and a data storage capacitor, the gray level of which is controlled by the data storage capacitor. The DDIC controls each pixel via the TFT, resulting in minimal power consumption and a long lifespan. Each pixel is made up of many sub-pixels that represent the three main RGB colors (R, G, and B).
The voltage of the pixels on the TFT is transferred one by one in a scanning manner according to a certain time rhythm. Some of the ICs in charge of scanning are DDICs, while others are in charge of horizontal scanning and others of vertical scanning.
Furthermore, DDICs require a chip responsible for job assignment, known as the Timing Controller, or T-CON for short, which is typically the most complicated chip in the display and may be regarded as the “\CPU of the display.
It is primarily responsible for analyzing the signal from the host computer, deconstructing it, changing it into a signal understandable by the Source/Gate IC, and then allocating it to the Source/Gate for execution. T-CON has this purpose since it has the power to alter the tempo of time that the Source/Gate does not, which is why it is referred to as a Timing Controller.
The rising resolution, refresh rate, and color depth put T-CON’s processing capabilities and the information transmission capability of various interfaces to the test.
The Global Panel Display Driver IC (DDI) Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Samsung Electronics has introduced a new display driver IC (DDI) that the company claims would improve the performance and economy of 8K televisions.
According to the business, the 36CT93P DDI has intra-panel data transmission rates of up to 4Gbps owing to its proprietary universal standard interface for TV (USI-T) 2.0. This is twice as fast as the previous generation’s USI-T 1.0.
The new DDI’s increased speed will improve display performance efficiency and eliminate the need for extra components like wires, enabling for smaller product designs in TVs bigger than 65-inches.
USI-T 2.0 now has a smart equalizer that can program all DDIs in a panel at the same time. Samsung is presently the world’s largest supplier of DDIs used in smartphones and televisions. The company’s System LSI business, which manufactures DDIs, has expanded its portfolio to include components for 5G, AI, and vehicles.
Last year at CES, the business was the first to show off an 8K TV that turned lower quality media into 8K.The South Korean electronics company is promoting 8K QLED TVs with its The Wall MicroLED TVs.
