Title:
DISPLAY DRIVING CIRCUIT AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/206628
Kind Code:
A1
Abstract:
Disclosed are a display driving circuit and a display device. The display driving circuit comprises a voltage converter (11) having at least one direct-current voltage output branch (L1, L2, L3, …, Ln), and a current sampler (12) which is provided on at least part of the direct-current voltage output branch (L1) in the at least one direct-current voltage output branch (L1, L2, L3, …, Ln), and used for measuring the magnitude of a current flowing through the direct-current voltage output branch (L1) and outputting an associated voltage relevant to the magnitude of the current at an output end. The output end of the current sampler (12) is connected with the voltage converter (11). The voltage converter (11) is used for adjusting, according to the associated voltage from the current sampler (12), a direct-current voltage output from the corresponding direct-current voltage output branch (L1) so that the magnitude of the current flowing through the corresponding direct-current voltage output branch (L1) is stable at a preset value relevant to a target output voltage value.
