The NT50358 is a specialized Integrated Circuit (IC) manufactured by Novatek Microelectronics.1 It is primarily utilized in mobile devices as a Power Management IC (PMIC) specifically dedicated to the LCD Display and Backlight systems.2
This IC is a common component in many popular mid-range smartphones from brands like Xiaomi (Redmi series), Oppo, Vivo, and Samsung (A-series).3 Its primary role is to regulate the voltages required to drive the LCD panel and manage the high-voltage requirements of the LED backlight string.

Key Features and Functional Description
The NT50358 is designed to handle the complex power requirements of modern mobile screens. Its architecture focuses on three main areas:
-
Display Bias Voltage: It generates the positive and negative voltages (often $+5V$ and $-5V$) necessary for the liquid crystal pixels to transition and maintain state.
-
Backlight Driving: It acts as a “Boost Converter,” stepping up the low battery voltage (approx. 3.7V) to the much higher voltage (up to 20V-25V) required to light up the LED backlight array.
-
Energy Efficiency: Given its application in mobile devices, the IC is engineered for minimal power leakage to preserve battery life when the screen is dimmed or off.
Common Fault Symptoms
When this IC fails, the phone usually exhibits specific “No Display” or “No Light” symptoms:
-
Black Screen: The phone vibrates or makes sounds, but the screen remains completely dark.
-
No Backlight: You can see icons on the screen if you shine a flashlight on it, but the screen doesn’t light up on its own.
-
Graphical Artifacts: Flickering or distorted colors caused by unstable bias voltages.
Repair and Installation Note
Because the NT50358 uses a BGA (Ball Grid Array) package, replacement requires professional SMD (Surface Mount Device) rework stations. It must be soldered using precise temperature profiles—typically around 330°C to 350°C—to avoid damaging the delicate internal silicon or the surrounding motherboard components.
