This pin synchronizes with the frame and the gate driver.
Fetching of display data starts when H is read at the rising edge of HCK.
This pin is the shift clock input of the gate shift register. The start pulse is captured at the rising
edge of clock and output the pulse at the falling edge.
Refer to the below “Circuits of touch panel”.
Refer to the below “Circuits of backlight”.
This pin turns on/off the BIAS circuit and turns on the output SW and amplifier. When AP is H,
the amplifier is set and the product is driving. The amplifier output and output SW are turned on
at the rising edge of AP, starting the product drive.
Note that the output SW is turned off at the rising edge of STB and the output becomes Hi-Z.
Connect “AP” to VCC, when the controller (part no.: S1L50282F23k100) is used.
This pin is the shift clock input of the column shift register. Display data is captured into the data
register at the rising edge.
This pin controls the output of the gate drivers. Output can be controlled regardless of VSP and
VCK.
A timing signal that latches the contents of the data register. When an H level is read at the rising
edge of HCK, the contents of the data register are latched and transferred to the D/A converter,
and analog voltage corresponding to the display data is output. Also, because the internal
operation via HCK continues even after the STB latch, do not stop HCK. The contents of the shift
register are cleared at the rising edge of STB.
