STP0350B1-320480 Series TFT LCD Display Screen Panel

Product Information: STP0350B1-320480(TN) TFT LCD PANEL

The STP0350B1-320480(TN) series TFT LCD panel is manufactured by Shenzhen Surenoo Technology Co., Ltd. The panel has a display format of graphic 320RGB*480 dot-matrix 320xRGBx480 with a transmissive display mode and 8bit/16bit interface input data. It is equipped with the ILI9488 drive and CTP: GT911 touch panel driver. The LCD panel measures 3.5 inches and has a viewing direction of 12 o’clock.

Mechanical Specification
The LCD panel has an active area of 48.96(W)73.44 (H) mm with a resolution of 320RGB480 dots. The pixel size is 0.153(W)0.153(H) mm. The CTP has a dimensional outline of 55.26(W)84.52(H)4.13(T) mm, while the RTP has a dimensional outline of 55.26(W)84.52(H)4.00(T) mm, and the NTP has a dimensional outline of 55.26(W)84.52(H)*2.70(T) mm.

Module Function Description
The TFT LCD PANEL has 26 pins, including GND, VDDA, VDDI, CSX, DCX, WRX, RDX, RESET, DB0-DB7, and DB8-DB15.

Electrical Maximum Ratings
The minimum and maximum supply voltage for VDDI is 1.8V and 3.3V, respectively, while the minimum and maximum supply voltage for VDDA is 2.8V and 3.3V, respectively. The operating temperature range is -20°C to 70°C, while the storage temperature range is -30°C to 80°C.

Brightness Characteristic & Power Dissipation
The LED module forward voltage has a minimum of 29V and a typical value of 3.1V with a maximum of 3.3V. The LED module current has no minimum value, a typical value of 128mA, and no maximum value. The LCD surface luminance has a typical value of 300 cd/m2, while the LCM surface brightness uniformity has a typical value of 0.39%. The LCD power dissipation varies depending on the voltage and current, with PLCD = VDD * (ILED+ILCD).

Product Usage Instructions

The STP0350B1-320480(TN) TFT LCD PANEL is commonly used in various electronic devices, including but not limited to smartphones, tablets, laptops, and other display devices. Before using the product, ensure that the device’s power supply voltage is within the specified range of 1.8V to 3.3V for VDDI and 2.8V to 3.3V for VDDA.

The LCD panel can be connected to the device using an 8bit or 16bit interface input data. The panel is equipped with the ILI9488 drive and CTP: GT911 touch panel driver. The touch panel driver can be used to provide touch functionality to the display device.

The LCD panel has 26 pins, including GND, VDDA, VDDI, CSX, DCX, WRX, RDX, RESET, DB0-DB7, and DB8-DB15. The pins can be connected to the device’s circuit board using the corresponding pin definitions.

When using the LCD panel, ensure that the operating temperature range is within -20°C to 70°C, while the storage temperature range is within -30°C to 80°C. The brightness and power dissipation values should also be considered when designing the device that will use the LCD panel.
