I. Resolution

Higher resolution results in a more detailed image, but also places higher demands on the motherboard's processing power and graphics card. 12.1-inch 4:3 aspect ratio LCD panels have two resolutions: 800×600 and 1024×768. Now, 1024×768 is more commonly used. 12.1-inch 16:10 aspect ratio LCD panels only have one resolution: 1280×800. We have provided the following models for your reference based on different resolutions.

1024×768 (XGA)	790K	Industrial control panels, medical monitoring, standard HMI	G121XCE-L02,EV121XM-N10, G121XN01 V0
1280×800 (WXGA)	1.02M	Advanced HMI, in-vehicle systems, digital signage	G121ICE-L02, G121EAN01.0, EV121WXM-N10

II. Interface

Most 12.1-inch TFT LCD panels use LVDS interface, which is widely compatible with industrial devices motherboards. If you prefer MIPI, eDP, RGB, or other interfaces, please send an inquiry to us for recommended models. If your motherboard's interface is incompatible, we also offer custom adapter board services. You can send an inquiry to us for customized interface adapter solutions to meet specific motherboard compatibility requirements.

III. Brightness

The choice of LCD screen brightness generally depends on the application scenario of your devices. If your device is intended for outdoor use, you need to determine whether it's a semi-outdoor scenario---your device will be used in areas with shade. Then a LCD screen with a brightness of around 800 nits is okay. If your device's screen is to be displayed under direct sunlight, then you'll need a high-brightness display with a brightness of 1000 nits or higher.

Selection Recommendations:

♦ For general workshops and offices → 400-500 cd/m² is sufficient.

♦ For semi-outdoor environments (with some shade) → around 800 cd/m².

♦ For full outdoor environments with direct sunlight → 1000 cd/m² or higher, or with high-brightness backlighting driver board.

♦ For 12.1-inch 800*600 LCD Panel semi-outdoor use, the following models are available: G121ACE-LH2, G121STN02.0, TCG121SVLPBANN-AN50

♦ For 12.1-inch 800*600 outdoor sunlight display panels, the following model is available: G121STN02.1, LQ121S1LG86

♦ For 12.1-inch 1024*768 LCD Panel semi-outdoor use, the following model is available: P1210XGF1MA01, G121XCE-l01, G121XN01 V0

♦ For 12.1-inch 1024*768 sunlight readable LCD display: TCG121XGLPBPNN-AN40, G121XCE-LH1, LQ121X3LG02

♦ For 12.1-inch 1280*800 LCD Panel Semi-Outdoor Use: LQ121K1LG58, G121ICE-L01, G121EAN01.0

♦ For 12.1-inch 1280*800 outdoor sunlight display panel: G121EAN01.3, G121ICE-LH1

IV. Operating Temperature

The operating temperature of TFT LCD panels determines the application environment of the device. Most 12.1-inch industrial TFT LCD displays meet the requirement of -20℃ to 70℃. If you do not have specific requirements for the temperature range, you can refer to other parameters for selection.

V. Viewing Angle

The viewing angle determines the display effect when multiple people are viewing the screen. If the equipment requires viewing by multiple people (e.g., medical consultations, monitoring centers), it is recommended to choose a wide-viewing-angle screen (≥85/85/85/85) using IPS or AHVA technology. If only one person is operating it directly in front, a TN screen (80/80/80/80) will suffice, and is more cost-effective.

Recommended models:

Wide viewing angle required → G121XCE-L02, G121EAN01.0, EV121WXM-N10

Normal viewing angle required → G121SN01 V403, ET121S0M-N11, LQ121S1LG75
