VLOD0 (0.3 V, typ)

VLOD1 (0.6 V, typ)

VLOD2 (0.9 V, typ)

VLOD3 (1.2 V, typ)

Table 9. LSD Threshold Voltage Truth Table

LSDVLT

BIT 126

BIT 125

LED SHORT DETECTION (LSD) THRESHOLD VOLTAGE

VLSD0 (0.35 × VCC, typ)

VLSD3 (0.65 × VCC, typ)

Table 10. LOD and LSD Data Latch Time Truth Table

LATTMG

BIT 128

BIT 127

LOD and LSD DATA LATCH TIMING

17th GSCLK after BLANK bit is changed to '0' or GS counter is reset.(1)

33rd GSCLK after BLANK bit is changed to '0' or GS counter is reset.(1)

65th GSCLK after BLANK bit is changed to '0' or GS counter is reset.(1)

129th GSCLK after BLANK bit is changed to '0' or GS counter is reset.(1)

(1)

When DSPRPT is '1' and IDMRPT is '0', the resulting LOD and LSD data are loaded to the LOD and LSD data latch only one time after

new GS data are written into the second GS data latch.
