A touch display panel is provided. The touch display panel includes: a display panel, a touch glass, and a touch controller. The display panel includes sensing lines and identification pins. The touch controller obtains first product information of the touch glass. The touch controller and the display panel respectively report the first product information of the touch glass and second product information of the display panel to a host. The host retrieves firmware and a default noise offset value corresponding to the touch display panel according to the first product information and the second product information, and writes the firmware and default noise offset value to a non-volatile memory of the touch display panel. The touch controller executes the firmware, and determines touch actions performed on the touch glass according to the default noise offset value.

An illuminance calibrating device includes a reference light source and an illuminance detection device. The reference light source, which generates light with a specific wavelength and a source illuminance, adjusts the source illuminance to be a first illuminance according to a control signal. The illuminance detection device includes a shading plate, an illuminance detector, and a controller. The shading plate is configured to lower the first illuminance to a first shading illuminance. The illuminance detector detects the first shading illuminance to generate a detection signal. The controller generates the control signal and calculates a ratio of the first illuminance to the first shading illuminance according to the detection signal.
