Display driver development
Controller drivers written against the panel and the processor interface you use.

Display drivers that hold up
on the panel you actually shipped.
A display is not a screen and a controller is not a driver. Panel timing, controller initialisation, backlight control and power states all interact, and a driver that works on the bench can flicker, overheat or damage a panel once it is in the enclosure.

- Timing & power states
- Backlight & touch integration
Why display problems are hard to pin downTiming errors look like
Timing errors look like
a driver problem, or worse.
A display that flickers, shows artefacts or refuses to wake may have a timing error, a power-sequence problem, coupling from a nearby switching stage, or a genuinely faulty panel. Without method these get confused, and the usual result is swapping parts until the fault appears to go away.
We work through the power sequence, timing parameters and interface one at a time, measuring on the real panel, so the cause is identified rather than guessed at.
Panel datasheets have limits, not just typicals. Timing and power are specified across temperature, and the design is verified at the limits rather than at room temperature.
- 01Real panel verified
Driver developed and tested on the actual panel in the enclosure, not on a warm bench display.
- 02Timing from the datasheet
Timing parameters taken from the panel specification and verified across temperature.
- 03Power states defined
Sleep, dim and wake behaviour designed so the panel and backlight are not stressed.
- 04Artefacts diagnosed
Flicker, tearing and image faults methodically isolated to timing, power or coupling.
- Panel-specificTiming and power taken from the panel datasheet rather than a copied example.
- Temperature checkedBehaviour verified across the temperature range, not only at room temperature.
- Power states definedSleep, dim and wake behaviour designed so the panel is not stressed.
- Faults isolatedFlicker, tearing and artefacts traced to timing, power or coupling rather than guessed at.

Panel and backlight power states designed to protect the panel and save power.
Discuss thisDisplay troubleshooting
Flicker, artefacts, wake failures and colour issues isolated and fixed.
Discuss thisWhat is included in scope
Scope is agreed in writing before work starts, so deliverables and responsibilities are clear.
- Panel & interface reviewPanel, controller, interface and processor side reviewed for compatibility.
- Power sequenceReset, supply rails and power-on sequence implemented to the panel requirements.
- Driver implementationController driver, timing and refresh written and tested against the real panel.

- Power statesSleep, dim and wake behaviour implemented and measured for current draw.
- Verification & handoverBehaviour checked across temperature, and the driver documented for maintenance.
Capabilities
Display driver capability
Display work is done against the panel, the controller and the enclosure together, because the fault rarely belongs to just one of them.
TFT & LCD drivers
Controller drivers, timing and refresh for common TFT and LCD panel families.
OLED & e-paper
Display drivers and power management for OLED and e-paper panels.
Frame timing
Refresh rate, blanking, tearing avoidance and update strategy for the interface.
Backlight control
Backlight driving, dimming strategy, PWM choice and safe power-off.
Touch integration
Touch controller drivers and input handling working with the display stack.
Power management
Panel and backlight power states designed for low power and panel longevity.
Colour & format
Pixel formats, colour correction and gamma handled for the panel characteristics.
Troubleshooting
Flicker, artefacts, wake and colour faults isolated methodically and fixed.
The screens themselves are built in GUI development, and panel modules in TFT driver products.

Technologies
Display technologies
Interface and controller choices follow the panel, the required refresh rate and the processor you have chosen.
- Panel familiesTFT, LCD, OLED and e-paper panels across common controller types
- InterfacesMIPI DSI, SPI, parallel RGB, LVDS and MCU-specific display interfaces
- Frame timingRefresh rate, blanking, tearing avoidance and partial update strategies
- BacklightLED backlight driving, dimming, PWM frequency and protection
- TouchCapacitive and resistive touch controller drivers and input handling
- Power & sleepPanel power states, current draw measurement and wake sequencing
Partial-refresh and e-paper panels can save substantial power, but only if the application avoids full-screen redraws. We design the update strategy alongside the driver rather than separately.

Ask about your requirements →What display driver development services do you offer?
Display driver development, frame timing and refresh, backlight control, touch and input integration, power and sleep state handling, and display troubleshooting.
Which display types do you support?
TFT, LCD, OLED and e-paper panels across common controller families, using interfaces such as MIPI DSI, SPI, parallel RGB and LVDS, depending on the processor and panel.
My display flickers or shows artefacts. Can you help?
Yes, and we approach it methodically. Timing parameters, power sequencing, coupling and the panel itself are checked in turn, because these symptoms are easily confused with one another.
Do you verify across temperature?
Yes. Display timing and power behaviour are checked across the operating temperature range, since panels frequently behave correctly at room temperature and badly at the limits.
Can you reduce display power consumption?
Yes. Backlight duty cycle, refresh strategy and panel sleep states are designed together and current draw measured before and after. For e-paper, update strategy matters as much as the driver.
Can you work with an existing display driver?
Yes. We can review an existing driver for timing accuracy, power sequencing, error handling and integration, then either fix the specific fault or rework it for reliability.
