TM035PDHG03

Product catalog summary

General Specifications
The TM035PDHG03 is a 3.5-inch display module with a resolution of 320(RGB) x 480, utilizing a-Si technology and a vertical stripe pixel configuration. It features a normally white display mode with HC surface treatment. The module measures 55.26 x 84.69 x 2.2 mm and weighs 21 grams. It supports MCU+RGB+SPI interfaces with a color depth of 65K/262K.

Input/Output Terminals
The module includes terminals for frame head pulse, data enable, pixel clock, sync signals, power, and data bus connections. Interface mode selection is available via IM0, IM1, and IM2 pins.

Absolute Maximum Ratings
Operating power voltage ranges from -0.3 to 3.3 V, with operational temperatures between -20 to 70°C and storage temperatures from -30 to 80°C. Humidity specifications are provided to prevent condensation.

Electrical Characteristics
Logic signal input/output voltage ranges from 1.65 to 3.3 V, with a power supply voltage between 2.65 and 3.3 V. Power consumption is 34.2 mW in black mode and 2.4 mW in sleep mode. The backlight unit has 6 LEDs with a forward current of 20 mA and a forward voltage of 3.2 V per LED.

Timing Chart
Detailed timing characteristics are provided for DBI Type B, 3-Line SPI, 4-Line SPI interfaces, DPI interface characteristics, and pixel formats.

Optical Characteristics
Viewing angles are 60-70 degrees for top, left, and right, and 50-60 degrees for bottom. The contrast ratio is 400-500, with response times of 25-35 ms. Chromaticity coordinates for white, red, green, and blue are included.

Environmental/Reliability Test
The module undergoes various tests to ensure performance under specified conditions.

Mechanical and Packing Drawings
Drawings provide detailed dimensions and packaging information.

Precautions for Use
Guidelines are provided for proper handling and use to ensure longevity and performance.

Specifications and Test Conditions
The TM035PDHG03 model by TIANMA MICRO-ELECTRONICS Corporation has a luminance of 250-300 cd/m² under NTSC 60 conditions. Tests are conducted at 25℃ with a current of 20mA, focusing on the center of the LCD screen in a dark room after 5 minutes of operation.

Optical Measurement Definitions
Definitions for optical characteristics such as viewing angle, contrast ratio, response time, color chromaticity, luminance uniformity, and luminance are provided.

Environmental and Reliability Tests
Tests include high and low temperature operations, storage conditions, humidity operations, thermal shock, electrostatic discharge, vibration, shock, and package drop tests, following standards like IEC60068 and GB/T2423.

Mechanical and Packing Drawings
Drawings detail dimensions and materials for the module and packaging, with a total packed weight of approximately 12.45 kg.

Handling, Storage, and Transportation Precautions
Handling precautions emphasize the fragility of the glass display panel. Storage recommendations include avoiding direct sunlight and maintaining a temperature range of 0℃ to 40℃ with humidity below 80%. Transportation precautions focus on preventing falls, shocks, and exposure to water or sunlight.
