Yousee Display module TFT LCD YX28007B
Yousee Display module TFT LCD YX28007B
The document details the specifications for the LCD module YX28007B by Shenzhen Yousee Technology Co., Ltd. It features a 2.8-inch a-si TFT display with a resolution of 240(RGB) x 320 dots. The module dimensions are 50.00(W) x 69.20(H) x 2.45(T) mm, with an active area of 43.20(W) x 57.60(H) mm. It uses a 4-wire SPI interface and operates at an input voltage of 2.8±0.1 V.
Detailed dimensions and layout for the module are provided, including recommendations for touch panel window placement and foam padding to prevent light leakage.
The interface consists of 10 pins, including power supply, ground, data/command select, chip select, clock input, data input/output, reset signal, and backlight LED connections.
The module operates within a supply voltage range of -0.3 to +4.6 V and a temperature range of -20 to +70°C. Storage temperature ranges from -30 to +80°C with a maximum humidity of 90% at 60°C.
Operating voltages for analog and logic circuits are specified, along with input and output voltage levels for high and low states.
The backlight consists of 4 white LEDs connected in series and parallel, with a forward voltage of 3.0 to 3.3 V at 80mA.
Details on response time, contrast ratio, color gamut, luminance uniformity, viewing angle, and surface luminance are provided, with specific testing methods and conditions.
Power on/off sequences for 2-power and 3-power configurations are outlined, with a note to refer to the IC specification for details.
Reset timing is provided for reference, with a recommendation to consult the IC specification.
A workflow chart describes the production process, including responsibilities, related files, and forms used. Emphasis is placed on maintaining records and handling nonconforming products according to established procedures.
Criteria for defects such as point and line defects, LCD corner and edge damage, and glass protrusion are specified, with allowable limits and defect categories.
Various tests are described, including high and low temperature storage, operating conditions, temperature cycling, damp proofing, and ESD testing, with post-test inspection criteria.
Handling precautions emphasize the fragility of the glass and polarizer, advising against excessive force, mechanical shock, and direct contact with bare hands to prevent damage and contamination.
Handle polarizers carefully to avoid scratches. Do not touch, push, or rub with anything harder than an HB pencil lead. Avoid placing objects on the display area to prevent marks. Condensation can damage the polarizer, so warm up products tested at low temperatures before exposing them to room temperature air.
Ensure soldering irons and other tools are properly grounded. The AC power source should not leak. Electric screwdrivers should be grounded to minimize electromagnetic interference.
LCMs are fragile and should be handled with care. Use anti-static gloves and handle by the edges. Avoid stacking LCMs or using sharp objects. Apply logic voltage before analog voltage when powering on, and reverse the order when powering off. Long-term display of the same pattern may cause ghost images, which can be resolved by resting the display.
Maintain specified temperature and humidity ranges to prevent polarization degradation and other issues. Store LCMs in sealed polyethylene bags in a dark place, avoiding direct sunlight and maintaining appropriate temperature and humidity levels.
Handle with care during shipment. Packaging should not be damaged, and carton stacking should not exceed two meters. Ensure waterproof and moisture-proof measures are in place.
The packing dimensions are 370*300*150.
Specifications are binding for quality inspection. Customers should report any issues or disagreements promptly. YX Technology is not responsible for damages due to neglect of precautions. A limited warranty covers functional defects for one year from the shipment date, unless otherwise agreed.
