Product code of MB Panels

FAQ #100991

 

The table below indicates the signification of the numbers and letter in the product code of the MB Panels:

PCD7.D4	5	7	B	T	C	F	#	#
	LCD dimensions		LCD Type	Front handling	Processor	Housing/mechanic	Customer version
Options	5	7	B= QVGA B/W or gray level	T=Touchscreen	C=Coldfire      (5257)	F=Flush 202x156
	3	5	S= QVGA Color (STN)	M=Touch + Std SBC keys	P=Coldfire     (5373)	G=Flush 268x156
			T= QVGA Color (TFT)	N=Touch + OEM Keys	A=Arm	H=Handheld
	1	0	V= VGA Color (TFT)	L=OEM Keys, no touch	Z=customer specific
	5	0	W= WVGA Color (TFT)
	1	2	D= SVGA Color (TFT)

Remarks

• The LCD dimensions are written in Inches. A PCD7.D457STCF does therefore have an LCD with a diagonal of 5.7".
• The PCD7.D410V (VGA) does have diagonal of 10.4" (and not 1.0"), and the PCD7.D412D (SVGA) does have a diagonal of 12.1". 
• The code described here does not apply for the S-Energy Manager (PCD7.DxxxE).

Resolutions

LCD Type	Resolution	Remark
QVGA	320 x 240	= Quarter VGA
VGA	640 x 480	= Video graphics array
WVGA	800 x 480	= Wide VGA
SVGA	800 x 600	= Super VGA

STN/TFT

STN
Super Twisted Nematic (STN) screens are an improvement over the original Twisted Nematic(TN) screens.
STN screens use a fluid with a greater twist (200° or more). It can be used in larger matrix displays and has better contrast and viewing range than TN.
Super Twisted Nematic LCDs use a passive matrix screen technology that has no active or controlling element inside the display cell.
Pixels are controlled by energizing the appropriate row and column drive lines of the matrix from outside the display, resulting in a slow frame rate.
STN screens have limited color range, and viewing angle (~15 degrees max).

TFT
With Thin Film Transistor (TFT) LCDs, each pixel is controlled by one to four transistors.
Typically one transistor is used for each of the RGB color channels.
Because of this direct control technique, TFT screens are sometimes called Active-Matrix LCDs.
TFT technology provides more accurate color control, allowing it to display more colors
TFT screens also offer a wider viewing angle range (30 to 70 degrees) than the other popular types of LCDs.
