TCG070WVLQAPNN-AN01 Kyocera 7.0" WVGA TFT LCD Module 800x480

TCG070WVLQAPNN-AN01 Overview

The Kyocera TCG070WVLQAPNN-AN01 is the 500 cd/m2 member of the 7.0-inch WVGA (800 x RGB x 480) TCG070WVLQAPNN family. It keeps the same active area of 152.4 x 91.44 mm and the same 40-pin parallel RGB input, but a stronger backlight so that the picture still reads when the machine door is open and workshop light falls on the screen. The AWV cell is normally black and transmissive, giving a 500:1 contrast ratio and 85/85/85/85 degree viewing without the grey wash that a TN panel shows from the side.

At 500 cd/m2 the module works as a daylight-margin panel: behind 3 mm of clear cover glass roughly 8 to 10 percent of the light is lost, and a 500 cd/m2 source still leaves around 450 cd/m2 at the eye. The 165 x 104.4 x 8.5 mm outline fits the usual 7-inch cut-out, and the matte anti-glare front keeps overhead lamps from turning the screen into a mirror.

Why 500 cd/m2 Works on the Shop Floor

• Daylight margin: a press or CNC operator often faces an open door with sky light behind; 500 cd/m2 keeps black text legible where a 350 cd/m2 module would fall into grey.

• Cover-glass loss absorbed: the extra luminance pays for the reflection and absorption of a protective window without changing the controller.

• Symmetrical AWV viewing: 85 degrees in all four directions means the same contrast for a tall operator and for a short one, and for left or right standing position.

• 500:1 contrast: black backgrounds around alarms and status icons stay dark instead of lifting to grey in bright rooms.

• Matte surface: diffuses lamp reflections so that reading does not depend on where the fixture is mounted.

• Long backlight rating: 100,000 hours with the same two-string WLED arrangement, still requiring an external constant-current driver.

Technical Specifications

Application Fit

• CNC and press operator panels: bright halls, open machine doors and frequent tool changes.

• AGV and forklift terminals: vehicle-mounted displays that meet changing light as the truck moves between aisles.

• Woodworking, textile and printing machines: shops with skylights and white walls where ambient light is high.

• Access and parking kiosks: outdoor-facing housings with a sealed window and a dimmed night mode.

• Agricultural and construction equipment cabs: partly shaded cabs where the panel is seen through a tinted window.

Optical and Thermal Design Notes

Heat. A 500 cd/m2 backlight produces more heat than the 350 cd/m2 version. Leave at least 10 mm of free air behind the module, avoid wrapping the rear in foam, and keep the driver away from the panel edge. In a sealed box the internal temperature can rise 10 to 15 degC above ambient; check that the resulting panel temperature still sits inside the -20 to +70 degC operating range.

Dimming. For night mode use a driver with high-frequency PWM rather than pulse skipping. Low-frequency PWM is visible to the eye and causes banding in camera-based inspection systems that look at the same machine.

Reflection control. If the panel is used behind a window, an anti-reflective coated glass removes most of the surface reflection; without a coating, the matte polariser alone still handles diffuse light well.

Connector and cable. A 40-contact, 0.5 mm pitch FFC is used. Route the cable away from the inverter or driver inductor, since the RGB lines are single-ended and can pick up switching noise.

Quality Inspection

Each unit is powered for a burn-in check, then inspected for bright and dark dots, mura, polariser defects and backlight uniformity. Luminance is sampled per batch to confirm that the panel still reaches its rated typical value, and the result is recorded against the serial range. Modules leave in ESD bags with edge foam.

Packing and Shipping

One module per anti-static bag, foam corners, rigid carton. Cartons are labelled with model, quantity and a fragile icon. Dispatch is from the Hong Kong warehouse with tracking; export paperwork is prepared for the destination.

FAQ

Q: Does 500 cd/m2 still work behind a cover glass?
A: Yes. Clear 3 mm glass costs roughly 8 to 10 percent of the light, so about 450 cd/m2 reaches the eye. With an anti-reflective coating the loss is lower.

Q: Can AN01 replace AN00 in the same bracket?
A: The footprint and connector are the same, but the AN01 outline is 8.5 mm deep against 8.2 mm for AN00. Check the rear clearance and the stand-off height before swapping.

Q: Is this an LVDS panel?
A: No. It uses parallel RGB, 1 channel of 6 bit, on a 40-pin connector with a 3.3 V logic supply.

Q: How much backlight current does it need?
A: The value is given in the panel specification and depends on the two-string arrangement. Set the driver to that current; do not drive the strings from a fixed voltage.

Q: Which variant is rated for very long duty?
A: AN04 carries the 100,000-hour backlight rating in the released specification. AN01, AN02 and AN00 use the same two-string WLED construction.
