Embodiment 1

[0102] Figure 4a Shown is a line scan signal monitoring circuit provided by Embodiment 1 of the present invention, and in actual application, the threshold input pin 6 of the 555 timer receives the positive pulse line scan signal provided by the drive controller, and the output pin 3 is directed to The drive controller feeds back the real-time monitoring results.

[0103] Specifically, such as Figure 8 and Figure 9 As shown, after turning on the external power supply, and without loading such as Figure 6 Before the normal positive pulse line scanning signal shown, the capacitor C1 is charged, and the voltage V at the first node a a rises when V a =2Vcc / 3, the synchronous RS flip-flop of the 555 timer outputs a low level, the discharge tube T is turned on, and the capacitor C1 is quickly discharged, so that the output voltage of the output pin 3 of the 555 timer is V o =0, at this time, the circuit of the 555 timer is in a steady state. at t = t 0 At this time, the t...

Embodiment 2

[0107] Figure 4b Shown is a line scan signal monitoring circuit provided by Embodiment 2 of the present invention, and in practical application, the trigger input pin 2 of the 555 timer receives the positive pulse line scan signal provided by the drive controller, and the output pin 3 is directed to The drive controller feeds back the real-time monitoring results.

[0108] Specifically, such as Figure 8 and Figure 9 As shown, after turning on the external power supply, and without loading such as Figure 7 Before the normal negative pulse line scan signal shown, the capacitor C1 is charged, and the voltage V at the first node a a rises when V a =2Vcc / 3, the synchronous RS flip-flop of the 555 timer outputs a low level, the discharge tube T is turned on, and the capacitor C1 is quickly discharged, so that the output voltage of the output pin 3 of the 555 timer is V o =0, at this time, the circuit of the 555 timer is in a steady state. at t = t 0 At this moment, the tr...

Abstract

The invention discloses a display driving system and a driving method thereof. The display driving system comprises a driving controller and a driving circuit as well as a line scanning signal monitoring circuit located between the driving controller and the driving circuit, wherein the line scanning signal monitoring circuit is used for monitoring whether a line scanning signal provided by the driving controller to the driving circuit is normal or not in real time and feeding the real-time monitoring result back to the driving controller; and the driving controller provides the normal line scanning signal again when receiving the real-time monitoring result when the line scanning signal is abnormal. As the line scanning signal monitoring circuit can monitor the line scanning signal provided by the driving controller in real time and feed the real-time monitoring result back to the driving controller, the driving controller provides the normal line scanning signal again when receiving the real-time monitoring result when the line scanning signal is abnormal, so that the fault signal is repaired, and the problem of an abnormal display picture caused by faults of the driving controller is solved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display driving system and a driving method thereof. Background technique [0002] Existing display products include a display drive system 101 and a display screen 102, and the display drive system 101 is mainly composed of a drive controller and a drive circuit, such as figure 1 shown. Among them, the drive controller is responsible for converting the content to be displayed into a format that meets the timing requirements of the drive circuit; the drive circuit selectively controls the brightness of each pixel according to the drive signal provided by the drive controller, and realizes the display of a specific picture on the display screen 102. show. [0003] Once a certain fault occurs in the drive controller, the drive circuit will realize the screen display according to the received fault signal, resulting in a display fault. Taking the most common 1 / 8 scan s...
