TCG070WVLQAPNN-AN00 Kyocera 7.0" WVGA AWV TFT LCD Module 800x480

TCG070WVLQAPNN-AN00 Overview

The Kyocera TCG070WVLQAPNN-AN00 is a 7.0-inch WVGA (800 x RGB x 480) a-Si TFT-LCD module built for equipment that runs continuously inside an enclosure. Its Advanced Wide View cell is a normally black, transmissive design, so the panel holds a 500:1 contrast ratio and a stable image from all four directions at 85 degrees, even when the operator stands off-axis at a machine door. At 350 cd/m2 typical luminance the module is tuned for indoor cabinets, control desks and instruments rather than direct sunlight, which keeps backlight heat and supply current modest in a sealed housing.

The module runs from a 3.3 V logic supply and accepts a 40-pin parallel RGB signal in 1 channel x 6-bit format, which matches the timing outputs of the industrial CPU boards and HMI controllers used in this equipment class. A matte anti-glare front polariser suppresses reflections from ceiling lights, and the 165 x 104.4 x 8.2 mm outline with a 152.4 x 91.44 mm active area follows the standard 7-inch mounting footprint.

Key Characteristics

• AWV, normally black cell: 85/85/85/85 degree viewing angle at CR >= 10, so contrast and colour stay usable across a wide operator position range.

• 350 cd/m2 typical luminance: balanced for indoor HMI, laboratory and building-services terminals where a brighter panel would add heat and current.

• 500:1 contrast ratio: deeper blacks than a TN module of the same generation, which helps thin fonts and trend curves stay legible.

• 6-bit RGB with FRC: 262K native colours shown as 16.7M, with 50 percent NTSC coverage for status graphics and simple machine visualisation.

• Two-string WLED, 100,000 hours: long service life, but there is no on-board constant-current circuit, so the driver has to come from the system.

• Matte anti-glare surface: removes mirror images of lamps and keeps fingerprints less visible.

• -20 to +70 degC operation: storage from -30 to +80 degC, suitable for unheated cabinets and cold starts.

Technical Specifications

Typical Applications

• Machine control panels: injection moulding, packaging and labelling machines where the display sits behind a sealed front plate.

• Laboratory and test instruments: bench equipment that needs stable grey levels for waveforms and trend display.

• Building automation terminals: access control, HVAC and energy monitoring units running around the clock in a wall box.

• Industrial PC front ends: fanless panel PCs whose thermal budget does not allow a brighter backlight.

• Retrofit of older 7-inch WVGA units: the outline and 40-pin RGB interface match many previous generation modules.

Integration Notes

Backlight drive. The WLED strings are brought out without a constant-current circuit. The system has to supply a regulated current source, and the current must be set from the panel specification rather than by applying a fixed voltage; driving the strings from a voltage rail shortens LED life and can cause uneven brightness.

Signal timing. The 6-bit RGB input accepts 262K colours natively. If the host outputs 8-bit per channel, the extra bits are dropped or dithered on the host side; the panel itself does not add dithering.

Mechanical mounting. Mount the module flat. Twisting the frame loads the COG bonds and the glass edges, and the front polariser should only be wiped with a soft cloth. A transparent protection plate is recommended when the panel is exposed at the machine front.

Connector. A 0.5 mm pitch FFC/FPC with 40 contacts is used; the mating connector must be latched and the cable routed so it cannot be pulled when the front door is opened.

Quality Inspection

Every module is checked for display function, uniformity, dot defects and backlight operation before packing. Units are handled with ESD protection, and inspection follows the Kyocera incoming-inspection criteria for bright and dark dots, polariser bubbles and foreign particles. Test records are kept per batch, so a reported issue can be traced to a serial range.

Packing and Shipping

Modules are packed individually in anti-static bags with foam edge protection, then in a rigid carton rated for air freight. Cartons are marked with model, quantity and handling icons. Shipments leave from our Hong Kong warehouse with tracking, and export documents are prepared for the destination country.

FAQ

Q: Is TCG070WVLQAPNN-AN00 a touch panel?
A: No. It is a display module without a touch sensor. A resistive or capacitive overlay can be added as a separate part, but the module has no touch controller.

Q: Can I drive the backlight directly from 12 V?
A: No. The two WLED strings need a constant-current driver. A 12 V rail may feed the driver, but its output current must be set to the panel specification.

Q: Why choose the 350 cd/m2 version over a 500 cd/m2 module?
A: In a closed cabinet the lower luminance keeps heat and current down, and 350 cd/m2 is still comfortable behind a tinted or anti-glare front plate. Take the brighter version only when ambient light at the screen is high.

Q: Does the 6-bit interface limit picture quality?
A: For machine graphics, trend curves and text it is sufficient. Photographs can show slight banding in smooth gradients; if that matters, dither on the host or use an 8-bit module.

Q: How do AN00, AN01, AN02 and AN04 differ?
A: They share the 7-inch WVGA footprint and 40-pin RGB interface. AN00 is the 350 cd/m2 version, AN01 and AN02 are the 500 cd/m2 versions, and AN04 is the 500 cd/m2 version released with the 100,000-hour backlight rating.
