Project Details

— Client Background

The customer designs and builds live streaming terminals for the interactive entertainment market (name withheld under NDA). The display is the primary user interface of the product: the host operates on-screen controls throughout a broadcast, so the touch panel has to respond reliably under continuous use, the image has to stay stable over long operating hours, and the screen has to remain readable from different positions in front of the terminal.

Because the module sits directly in the front face of the product, the cover glass is supplied as a customized part rather than a catalog item, so that the visible outline and surface finish match the enclosure the customer had already tooled.

— Solution Provided

Touch display matched to the terminal's landscape layout

A 4.3-inch IPS TFT panel with 480 x 800 resolution, 16.7M colors and 80/80/80/80 viewing direction. The panel is a portrait-format part that is mounted in landscape orientation in the streaming terminal, so the interface stays readable from the operator's position and from the audience side of the device.

Capacitive touch built for continuous operation

A G+F+F capacitive touch stack with a 0.7 mm cover lens, 6H surface hardness and transmittance of 87% or above, delivering the scratch resistance and light transmission required by a device that is touched for hours at a time.

Compact high -speed interface

A 2-lane MIPI DSI interface keeps the pin count low while supporting the 480 x 800 resolution, which simplifies the FPC and the connector layout inside a slim consumer terminal.

Customized mechanical integration

Module size of 66.26 x 113.9 x 3.35 mm with an active area of 56.16 x 93.6 mm; the cover glass outline, printing and interface configuration are matched to the customer's product so the display integrates into the existing front panel.

Environmental and reliability design

Operating temperature -20 degC to +70 degC, storage -30 degC to +80 degC, 8 white LED serial backlight, and RoHS-compliant material selection.

Testing and verification

Test Item	Condition
High temperature storage	80 +/- 2 degC x 96 hours
Low temperature storage	-30 +/- 2 degC x 96 hours
High temperature operating	70 +/- 2 degC x 96 hours
Low temperature operating	-20 +/- 2 degC x 96 hours
Thermal cycle (storage)	-20 degC (30 min) / 25 degC (5 min) / 70 degC (30 min), 10 cycles
Damp proof test (storage)	50 +/- 5 degC, 90% RH x 96 hours
Vibration test	10 Hz - 55 Hz - 10 Hz, amplitude 1.5 mm, X / Y / Z axes, 3 hours total (packing condition)
Drop test	1 m drop, one time per carton side (packing condition)
ESD test	+/- 8 kV, air mode, 10 times

Acceptance after each test: no air bubbles in the LCD, no seal leak, no non-display or missing segments, no glass crack, current within twice the initial value, surface free from damage, and electrical characteristics within specification. Outgoing inspection follows MIL-STD-105D Level II sampling with AQL limits defined for major and minor defects.

— Project Results

The customized configuration was frozen as a released specification (V0) covering the display, touch stack, interface and mechanical outline, so the module can be reordered against a controlled document.
The module passed the full reliability sequence above, including 96-hour high and low temperature storage, 96-hour operating tests, 10 thermal cycles, damp proof testing, vibration, carton drop and +/- 8 kV air discharge ESD.
Material selection complies with RoHS, which the customer's product compliance file requires.
The same 4.3-inch touch display platform is also used in other equipment categories, which keeps the supply chain and the engineering base common across products.

Customer Testimonials

"The touchscreen is operated continuously during a live session, so responsiveness is not a nice-to-have.

The panel keeps up with fast tapping over hours of use, and we have not had touch complaints from users."

Product Manager

live streaming equipment manufacturer

"We mount this panel in landscape, and the full viewing angle is what makes it work:

the interface stays readable whether the user is standing at the terminal or watching from the side."

Hardware Engineer

consumer electronics

"The cover glass was made to our outline, so the display sits flush in the front panel without a separate bezel. That saved us a tooling change."
