Product catalog summary

General Description
The document describes the TTH189BVG-01, a 1.89-inch TFT display module with a resolution of 320x386 pixels, capable of displaying 262K colors. It features a transmissive type color active matrix TFT LCD with amorphous silicon TFT as a switching device, including a driver circuit and back-light unit.

Module Parameters
The display measures 1.89 inches diagonally with an IPS/Transmissive/Normally Black mode. The active area is 29.57mm by 35.67mm, and the module outline is 31.58mm by 39.32mm by 1.6mm. It supports a QSPI interface and uses the GC9B71 driver IC. The luminance is 400 cd/m², with a contrast ratio of 800:1 and a color gamut of 60%.

Mechanical Drawings
Mechanical drawings are provided to illustrate the module's structure.

Module Interface
The interface includes pins such as LEDK, GND, TE, SDA0-3, CLK, CS, RESET, IOVCC, VCC, and LEDA for power supply, data transmission, and device reset.

Application Circuit
The recommended backlight circuit requires a constant current circuit, with a suggested current of 15mA to 20mA per LED, using the AW9364 IC as a reference.

Absolute Maximum Ratings
The module operates within a supply voltage range of -0.3V to +4.6V, with storage temperatures from -30ºC to +70ºC and operating temperatures from -20ºC to +60ºC.

Electrical Specification
DC characteristics include a supply voltage of 2.4V to 3.3V, with specific input and output voltage levels for logic states. Current consumption is detailed for normal and standby modes.

Initialization Code
Initialization code is provided for setting up the display module, including necessary commands and data sequences.

Optical Specifications
Optical characteristics are measured at 25ºC with a VDD of 2.8V. The luminance is specified at 450 cd/m², with a contrast ratio of 1000 to 1200. Viewing angles are 85 degrees horizontally and vertically.

Quality Assurance
The quality assurance section outlines standards to ensure product quality, including inspection specifications and defect classification.

Quality Assurance Discrepancies
Procedures for addressing discrepancies between Tailorpixels' QA standards and customer standards are outlined, including additional requirements and special problems.

Product Visual Inspection Standards
Visual inspections must be conducted under specific lighting conditions (1000-1500 lx) and viewing angles (45° from vertical). Inspection areas are defined as Active Area (A Zone) and Viewing Area (B Zone). A sample set indicating acceptable quality levels must be agreed upon in case of disputes.

Inspection Specifications
The sampling plan follows GB/T2828.1-2012/ISO 2859-1:1999 and ANSI/ASQC Z1.4-1993 standards, with major defects having an AQL of 0.4 and minor defects an AQL of 1.0. Criteria for defects such as black/white spots, scratches, and glass cracks are provided.

Defect Classification
Visual defects are considered minor, while electrical defects are major. Units with illegible or incorrect markings are rejected.

Packing Requirements
Packaging must prevent damage and include correct labeling, with materials offering ESD protection.

Reliability Specifications
Tests include constant temperature and humidity, high and low temperature operations, thermal shock, and ESD tests, with specific conditions and cycle times detailed.

Precautions and Warranty
Safety precautions include careful handling of liquid crystals and avoiding strong impacts. Instructions emphasize appropriate cleaning methods and avoiding static electricity. The warranty covers repair or replacement for defects within one year of shipment.

Packaging and Prior Consultation
Packaging details are to be determined. Tailorpixels reserves the right to change materials or processes for standard products without prior notice, but will consult customers for OEM products if changes affect product properties.
