DT024CTFT & DT024CTFT-TS

Product catalog summary

Introduction
The DT024CTFT and DT024CTFT-TS are 2.4-inch TFT display modules with a resolution of 240RGBx320 dots. They utilize the Ilitek ILI9341 driver, capable of displaying 262K colors. The driver is mounted on the glass and connected via FPC.

General Specifications
The display is transmissive with a diagonal size of 2.4 inches. It operates optimally at a 6 o'clock viewing direction and supports MCU parallel/RGB interface types. The module operates within a temperature range of -20°C to 70°C and can be stored between -30°C and 80°C. It is RoHS compliant.

Mechanical Drawing
Detailed mechanical drawings are provided for both DT024CTFT and DT024CTFT-TS models.

Interface Description
The module includes various pins for connection, such as reset, frame synchronizing, line synchronizing, and data enable signals. It supports an 18-bit parallel bi-directional data bus.

Absolute Maximum Ratings
The module can handle a power supply voltage between -0.3V and 4.6V and operates within a temperature range of -20°C to 70°C. Exceeding these ratings may cause permanent damage.

Electrical Characteristics
The power supply voltage ranges from 2.5V to 3.3V. Input and output voltage levels are specified for both high and low states.

Backlight Specification
The backlight operates at a forward current of 20mA with a typical supply voltage of 9.6V. Uniformity and color coordination are specified.

Optical Characteristics
The display offers a brightness of 220 cd/m² and a contrast ratio of 350. Viewing angles and response times are detailed, with specific chromaticity coordinates provided.

Safety Precautions
The document outlines handling, power supply, operating, and mechanical/environmental precautions to prevent damage and ensure safe operation. It emphasizes ESD precautions, proper soldering techniques, and avoiding direct sunlight exposure.

Displaytech Ltd LCD MODULE DT024CTFT / DT024CTFT-TS Version: 1.0 DT024CTFT and DT024CTFT-TS is a display module that contains a TFT display with a 320 * 240 RGB resolution. The driver used for this project is the Ilitek ILI9341 or compatible and can display 262K colors. The driver is mounted on the glass and the interconnection via FPC including components to drive the display module. (1) Serial interface is available, but not recommendable, as the speed of it is very slow. (2) Recommended mating connector: Hirose FH19SC-45S-0.5SH, FH12S-45S-0.5SH; or (3) Color tune may be changed slightly by...

The data are measured after LEDs are turned on for 5 minutes. LCM displays full white. The brightness is the average value of 9 measured spots. Measurement equipment PR-705 (Φ8mm) Measuring condition: - Measuring surroundings: Dark room. - Measuring temperature: Ta=25°C. - Adjust operating voltage to get optimum contrast at the center of the display. Measured value at the center point of LCD panel after more than 5 minutes while backlight turning on. The luminance uniformity is calculated by using following formula. ∆Bp = Bp (Min.) / Bp (Max.)×100 (%) Bp (Max.) = Maximum brightness in 9 measured...

DT024CTFT / DT024CTFT-TS Version: 1.0 Note 4: The definition of contrast ratio (Test LCM using PR-705): Luminance When LCD is at “White” state Luminance When LCD is at Black state (Contrast Ratio is measured in optimum common electrode voltage) Note 5: Definition of Response time. (Test LCD using DMS501): The output signals of photo detector are measured when the input signals are changed from “black” to “white” (falling time) and from “white” to “black” (rising time), respectively. The response time is defined as the time interval between the 10% and 90% of amplitudes. Refer to figure as below....

Displaytech Ltd11. Safety PrecautionHandling precautions: • This device is susceptible to Electro-Static Discharge (ESD) damage. Observe Anti-Static precautions. • Identify and, at all times, observe absolute maximum ratings for both logic and LC drivers. Note that there is some variance between models. • Prevent the application of reverse polarity to VCC and GND, however briefly. • Use a clean power source free from transients. Power up conditions are occasionally “jolting” and may exceed the maximum ratings of the modules. • The VCC power of the module should also supply the power to all devices...
