Previously we have explained what the AU Optronics and LG Phillips model numbers mean. This time, we will explain the naming system behind CHIMEI Optronics LCD model numbers.
From Wikipedia:
“Chi Mei Corporation is part of a privately held holding company called the Chi Mei Group, which has numerous subsidiaries. The new Chimei Innolux Corporation is the world’s No. 2 and Taiwan’s No. 1 largest maker of TFT-LCD panels.”
The common structure for the LCD model numbers is that they start with a 1-4 character code, which corresponds with the manufacturer (LTN for Samsung, LP for LG Phillips), etc.)
There are two types of model numbers: the old and new style.
Note!: The information provided is subject to change at the discretion of the manufacturer at any time. Typically the convention changes every manufacturing cycle and the only common indicators that can be generalized as permanent are the Manufacturer Code (N = ChiMei) and the size of the LCD: 133 = 13.3″, 156 = 15.6″.
Old-style model numbers.
Example 1: N156B3-L01
N – means the screen is made by Chi Mei
156 – means the size of the screen is 15.6″
B – means it has an HD (1366×768) resolution
3 – means the screen has a CCFL backlight type
Example 2: N156B6-L0A
N – means the screen is made by Chi Mei
156 – means the size of the screen is 15.6″
B – means it has an HD (1366×768) resolution
6 – means the screen has an LED backlight type
Example 3: N156O6-L01
N – means the screen is made by Chi Mei
156 – means the size of the screen is 15.6″
O – means it has an HD+ (1600×900) resolution
Example 4: N133L6-L01
N – means the screen is made by Chi Mei
133 – means the size of the screen is 13.3″
L – means it has a lower than HD resolution (1280×800 or 1024×600)
6 – means the screen has an LED backlight type
New-style model numbers.
Example 1: N156BGE-L31
N – means the screen is made by Chi Mei
156 – means the size of the screen is 15.6″
BGE – means it has an HD (1366×768) resolution
L (in -L31) – means the screen has a 40-pin LED connector
Example 2: N156BGE-E31
N – means the screen is made by Chi Mei
156 – means the size of the screen is 15.6″
BGE – means it has an HD (1366×768) resolution
E (in -E31) – means the screen has a 30-pin LED connector
Example 3: N156HGE-LB1
N – means the screen is made by Chi Mei
156 – means the size of the screen is 15.6″
HGE – means it has a Full HD (1920×1080) resolution
L (in -LB1) – means the screen has a 40-pin LED connector
Example 4: N116HSE-EA1
N – means the screen is made by Chi Mei
116 – means the size of the screen is 11.6″

I would like to make a correction and if possible also verify this:
For old style model numbers, for smaller screens (i.e. 10.1 inch), the L in N101L06 is a 1024×600 resolution and not 1366×768. The 1366×768 resolution only applies to larger screens (i.e. 13.3 inch example).
What are the differences between EA1, EAA, EBA (for example N140HGE-EAA, N140HGE-EA1, N140HGE-EBA)? All of these works on a laptop with N140HGE-EAA?
When it comes down to exact model specifics, these are generally reproduction runs of the screens, however they may also indicate a performance revision. You can view full specifications of a screen from websites such as http://www.panelook.com/index.php
I have a ChiMei N156B6-L0A, but I noticed there are different revision numbers like C2 and C3. What is the difference between Revision C2 versus Revision C3? Is the C3 an upgrade over C2? Please let me know. Thank you.
