The invention discloses an automatic
flicker adjusting device for a total reflection
liquid crystal display. A bracket is provided with a multidirectional knob and an adsorption base to realize size
adaptation of the display; the
signal connection
system comprises a high-speed serial
bus interface board, the input end of the high-speed serial
bus interface board is connected with an external control mainboard to receive a
control signal, and the output end of the high-speed serial
bus interface board is divided into two paths: the first path drives the
light source unit of the front light panel module, and the second path transmits a brightness
data signal; the detection and
control system comprises an optical sensor and a main
control unit, the optical sensor collects brightness data of the display, and the main
control unit executes
frequency domain analysis on a brightness
signal to calculate a
flicker rate and dynamically adjust a driving
voltage parameter of the display; and feeding back an iterative adjustment parameter based on the optical sensor through a closed-loop feedback mechanism until the
flicker rate meets a
target range, and finally writing an optimization parameter into a nonvolatile memory of a display controller. While the visual display stability and the long-term reliability are improved, the collaborative optimization of the
production line calibration efficiency and the
system adaptive ability is achieved.
