1. PURPOSE
1.1. This application note provides information for transitioning from the T-51382-series 6.4-inch thin
film transistor (TFT) display to the T-51750-series 6.5-inch display. This document identifies
performance and specification differences as well as instructions for direct replacement.
2. T-51750 ERRATA SPECIFICATIONS
2.1. Section 1 of reference (a) identifies the LCD type as normally-white mode / transflective which is
not correct. The display is normally-white mode / transmissive.
3. T-51750-SERIES & T-51382-SERIES GENERAL DIFFERENCES
3.1. Table 1 identifies major characteristics of the T-51750 and T-51382 display families. The T-
51750-series are smaller, more power efficient, and higher performing display over the series it
replaces.

Notes
T-51750 larger pixel increases
aperture ratio which improves color
and contrast.
T-51750 has 4% larger area.
15% length reduction
4.5% width reduction
4% height reduction
43% reduction in weight.
AG – anti-glare coating for reduced
reflections (matte surface)
AR – anti-reflective coating to reduce
glare (caused by index of
refraction differences) and
improve sunlight readability (AR
coating is a specular surface)
Symmetric display and reverse scan
capability allow selection of best
viewing direction (6:00 or 12:00)
by rotating display and reversing
the image.

T-51750-SERIES APPLICATION NOTE
4. T-51750-SERIES & T-51382-SERIES MECHANICAL DIFFERENCES
4.1. The T-51750-series display outer dimensions are smaller than its predecessors, but has a larger
active area. The display is also symmetric about its horizontal and vertical centerlines.
Symmetry allows display rotation to alter the viewing angle without requiring housing re-design.
Customers do not need to stock different part numbers to have 6:00 and 12:00 viewing displays.
See reference (c), Table 1, Figure 1 and Figure 3.

5. T-51750-SERIES & T-51382-SERIES ELECTRICAL DIFFERENCES
5.1. The T-51750 can accept 3.3 V or 5 V logic and power. The T-51382-series are 5 V devices. This
power supply change alters the absolute maximum ratings and electrical characteristics.

5.2. The T-51382-series offered alternative display resolutions based upon the polarity of the Vsync
and Hsync signals. The display modes are: VGA-480, VGA-400, VGA-350, and freedom-mode.
In these modes, the 640x480 display centers the smaller format on the screen with black bars to
the top and bottom. The T-51750-series does not provide this function.
5.3. The T-51750-series use the Hirose DF9B-31P-1V and T-51382-series use the Hirose DF9A-31P-
1V. Both are male, 31-pin, 1 mm pitch connectors with unique orientation keying. The difference
between the two part numbers are connector features:
DF9A-31P-1V – Has a mounting boss, but no mating retention features.
DF9B-31P-1V – Does not have a mounting boss, but has a metal fitting for positive retention.
Please see Figure 2.
