A touchscreen can look perfect and still fail in the field: accuracy drifts, a controller glitches under noise, or the sensor degrades after thousands…
Read the noteThe touch controller is where a touchscreen becomes usable: it measures the sensor, filters noise, tracks fingers, and reports coordinates to your host. Choose…
Read the noteTouch screen ESD and EMI immunity depends on controlling noise at its source, blocking coupling paths, and safely diverting transient energy before it reaches…
Read the noteEmbedded DisplayPort (eDP) is the preferred internal interface for custom 2K and 4K TFT displays because it transports far more video data through fewer…
Read the noteGMSL and FPD-Link enable automotive displays to carry uncompressed high-definition video, control data, and sometimes power between a domain controller and a remote LCD…
Read the noteThicker IK10 glass weakens touch coupling in inverse proportion to thickness. See the trade-off, its limits, and the impact test evidence to request.
Read the noteAn HDMI controller must generate more pixel clock than resolution x refresh suggests. See the timing arithmetic and the mode evidence to request.
Read the noteTurn resolution and refresh rate into a data-rate number, match it to a real display module, and record the checks before display design freeze.
Read the notePick the TFT LCD module interface your processor natively supports, then check resolution, bandwidth, cable length and the part's temperature grade.
