Advanced Product Information
Signal Driver
258-Channel, 6-Bit Signal Driver Applications
WFP6540B 6-bit, 258-channel signal driver designed 11.x 12.x chip-onglass (COG) TFT-LCDs. WFP6540B's minimum form factor optimized layout permit design high-display-quality, low-power 6-bit TFT-LCD's with minimum bezel area. WFP6540B's internal architecture includes resistor-string with value individual resistor segments weighted reduce signal driver power dissipation much when compared non-weighted resistor string architectures.

When LD258_1 `1', data loaded from Channel VS258 VS1. ENABLE IN/OUT: EIO1# EIO258# active `low' signals initiate loading data into Input Register WFP6540B. When EIOx# pads configured input, other configured output, with direction determined LD258_1 input (see Table 5-1). EIOx# output pads designed connected EIOx# input pads adjacent devices allow series drivers operate sequentially. When `low' applied EIOx# configured input first device series, data loaded from three sets 6-bit Data Inputs into first three 6-bit Input-Register locations. subsequent transitions DCLK, data continues loaded into remaining 6-bit Input-Register locations. When register full (258 words), EIOx# configured output goes `low', enabling next driver. data load sequence summarized Table 5-1, Figure Figure 5-2.

258-Channel Signal Driver TFT-LCDs Name VS1-VS258 Number 42-300 Type Description (Cont.) VOLTAGE OUTPUTS: These outputs drive pixel inputs simultaneously after high-to-low transition Outputs high impedance while high. DATA: Data inputs consist 6-bit words each three channels. falling edge DCLK, three 6-bit words three adjacent channels loaded parallel. Each data represented where: indicates channel indicates significance each word. indicates indicates input word. Latch Pulse: When asserted, data transferred from Input Register into Storage Register, selected analog voltages drive LCD. EIOx# output reset `high' level. DATA CLOCK: Data loaded into input registers high-to-low transition DCLK 2xCLK= both rising falling edges DCLK 2xCLK high. CLAMP: CLAMP# input controls active pulldown devices which present DCLK D00-D inputs. When CLAMP# signal drives low, these clamp devices connect DCLK WFP6540B's through impedance. CLAMP# should connected VDDD applications where level shifting used (i.e. when VCOM modulation employed). DIGITAL SUPPLY VOLTAGE: Either should provided this supply digital power device. ANALOG SUPPLY VOLTAGE: should provided this supply analog power device. REFERENCE ANALOG VOLTAGE INPUTS: These nine inputs used supply adjustable-reference voltage inputs resistive-string provide transmissivity-voltage response required each type LCD. Note: both pads must connected each other same potential; also, both pads must connected each other same potential
