A wide variety of devices, including big-screen TVs, desktop monitors, laptops, tablets, smartphones, and auto displays, employ display drivers.
An LCD or OLED display panel and a CPU or other digital system are connected by an AMOLED display driver IC.
In order for the display panel to produce the desired texts or images, display drivers normally accept commands and data and generate signals with the proper voltage, current, and timing.
Variations in the production and packaging of display panels might result in the display panels deviating from their intended standards, lowering the level of uniform display quality.
To account for variations in chips, NVM IPs can be used in AMOLED display driver IC to hold settings for brightness levels, contrast levels, color correction tables, and more.
The Global AMOLED 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.
An active matrix organic light emitting diode AMOLED display driver IC is described with a hybrid driving approach to fulfill rapid driving speed, high TFT current accuracy, and a high aperture ratio.
This driver IC enables real-time thin-film transistor (TFT) nonuniformity adjustment.
A mobile UHD (3840 x 2160) AMOLED display driver IC screen is driven by the suggested hybrid column-driver IC with one horizontal time of 7.7 s at a scan frequency of 60 Hz, while simultaneously sensing the TFT current for back-end TFT variation correction.
Each pixel uses a straightforward 3T1C pixel circuit due to external compensation.A suggested current-sensing circuit guarantees accurate current sensing and good panel noise immunity.
The driver incorporates an 8 bit current-mode ADC to evaluate the OLED V-I transfer characteristic for OLED luminance-degradation compensation by reusing the hybrid column-driver circuitries.
According to test results, the hybrid driving method lowers the maximum current error between two simulated TFTs with a 60 mV threshold voltage difference to 0.94 gray levels (37 nA) in 8 bit gray scales from 12.82 gray levels (501 nA).
The current-mode ADC with circuit reuse achieves 0.56 LSB DNL and 0.75 LSB INL.
