MXED202

128-Channel OLED Row Driver

Preliminary

FEATURES:

OVERVIEW:

• For all Passive-Matrix Organic Light Emitting

Diode (OLED) Displays

• Monochome and Color

Clare Micronix’s MXED202 is a row-multiplexed

display driver for OLED panel displays. The

MXED202 directly supports up to 128-row OLED

panel displays, or can be cascaded for controlling

additional rows. The MXED202’s low “on” switch

resistance ensures uniform luminance at rapid row

scan rates. This is the first production row driver

for OLED display OEM’s, enabling the development

and production of this new standard in flat-panel

display technology.

OLED Column Drivers

FUNCTIONAL DESCRIPTION:

MXED102 or similar column driver, or a controller.

In “normal mode” (single token), the token may be

entered at either end of the MXED202 row shift

rection selection control “Shift Right” (SHR). The

token bit is shifted one row (one channel) per clock

cycle (CLK), during which time only one row maxi-

mum is active at a time. In “dual mode” (DUAL),

the token bit is entered at one end and automati-

cally in the center, and again the token bits may be

selectively shifted left or right at the CLK rate; dur-

ing which time only two rows maximum are active

at a time. The MXED202 may be used for either

128- or 120-row display panels. When the “Select

128” (S128) control input is low, the MXED202 is

set for 120 outputs. When S128 is low, Rows 4

through 123 must be used. (Note: A lesser num-

The MXED202 is capable of sinking current for up

to 128 rows (LED cathodes) of an OLED display.

One or two outputs may be active at a time. For

displays requiring more than 150mA sink current

per row, multiple MXED202’s may be placed in

parallel.

Device settings, such as token direction, number

of active rows, dual or single-token mode, and oth-

ers, are set by dedicated input pins.

Figure 1 is a block diagram of the MXED202. Each

row output has two possible sources: ground, to

turn the LED on, and VOH (Voltage Output High) to

turn the LED off. To begin a scan of the rows, the

user inputs a token bit so that it is high at the rising

edge of CLK, which is typically provided by the
