### **Pros and Cons of buying a LG 14T90N-DP Gram LCD 14" Touch Display (14T90N-R.AAS9U1)**

The LG 14T90N-DP is a compact, lightweight industrial touch display designed for embedded applications, IoT, and automation systems. Its key advantages include:

1. **Compact and Lightweight Design**

The display is small (14-inch diagonal) and weighs around **1.5 kg**, making it ideal for space-constrained environments or portable applications. Its slim profile (10.5 mm depth) allows for easy integration into machinery or control panels.

2. **High-Resolution Touchscreen**

The **1280x800 (WXGA) resolution** provides clear, sharp visuals for data presentation, HMI (Human-Machine Interface) applications, or media playback. The **10-point capacitive touch** ensures responsive and accurate user interaction, supporting multi-touch gestures where applicable.

3. **Wide Operating Temperature Range**

With a temperature range of **-20 C to 60 C**, the display is suitable for industrial environments where extreme conditions (e.g., factories, outdoor kiosks, or cold storage) are common. This makes it more durable than many consumer-grade displays.

4. **Robust Build Quality**

The display features an **aluminum front bezel** and a **durable glass touch surface**, which enhances resistance to scratches and impacts. It also includes **IP65-rated protection** (dust and water resistance), making it suitable for harsh environments like manufacturing plants or outdoor installations.

5. **Multiple Connectivity Options**

- **VGA (analog) and HDMI (digital) inputs**, allowing flexibility in connecting to PCs, embedded systems, or media players.

- **RS-232 serial port** for direct communication with industrial controllers or PLCs.

- **USB Host/Device ports** for peripheral connectivity (e.g., keyboards, storage devices, or USB-based HMI software).

- **Ethernet (10/100 Mbps)** for network integration, enabling remote monitoring or updates.

This makes it versatile for both standalone and networked applications.

6. **Low Power Consumption**

The display operates efficiently, consuming **

7. **Embedded Linux Support**

The display runs on **Linux OS**, allowing for custom software development, embedded applications, or integration with open-source HMI frameworks like **Qt or Eclipse Kura**. This is advantageous for developers building specialized industrial interfaces.

8. **Backlight Options**

The display supports **white or amber backlighting**, which can be useful in applications requiring visibility in low-light conditions (e.g., amber backlight for nighttime readability in outdoor kiosks).

9. **Mounting Flexibility**

The display includes **VESA 75x75 mounting holes**, allowing for wall, panel, or stand mounting. It also has **adjustable brackets** for easy installation in tight spaces.

10. **Long Lifespan and Reliability**

LG s industrial-grade components and robust construction suggest a **long operational lifespan**, reducing long-term replacement costs. The lack of moving parts (except the touch panel) minimizes mechanical failure risks.

---

1. **Limited Brightness for Outdoor Use**

The maximum brightness is ** 300 nits**, which may be insufficient for direct sunlight applications. For outdoor or high-ambient-light environments, a higher-brightness display (e.g., 500 nits) would be preferable.

2. **No Built-in Wi-Fi or Bluetooth**

The display lacks wireless connectivity, requiring wired Ethernet for network access. This can be a drawback in applications where wireless flexibility is needed (e.g., portable kiosks or IoT devices).

3. **No Touch Calibration Tools**

Unlike some consumer-grade touchscreens, the LG 14T90N-DP does not include built-in calibration software. Users may need to manually calibrate the touch panel, which can be time-consuming for precise applications.

4. **Limited Audio Output**

There is **no built-in speaker or audio output jack**, making it unsuitable for applications requiring sound (e.g., multimedia playback or voice feedback systems).

5. **No Touch Screen Protection Film**

The touch surface is not pre-installed with a scratch-resistant or anti-glare film, which could lead to faster wear in high-touch environments. Users may need to purchase and apply these accessories separately.

6. **No Touch Screen Gestures (Advanced Multi-Touch)**

While it supports 10-point touch, it may not fully support advanced multi-touch gestures (e.g., pinch-to-zoom, swipe navigation) unless customized through software. This limits its usability in touch-centric consumer applications.

7. **No Touch Screen Pen Support**

The display does not natively support **stylus input**, which could be a drawback for applications requiring precise input (e.g., digital signage with annotations or industrial drawing interfaces).

8. **Limited Software Support**

The display runs on a basic Linux OS, which may lack pre-installed industrial HMI software (e.g., Siemens TIA Portal, Wonderware). Users may need to develop or integrate their own software, increasing development time and complexity.

9. **No Touch Screen Auto-Brightness**

The backlight brightness is not automatically adjusted based on ambient light, which could lead to eye strain in varying lighting conditions.

10. **No Touch Screen Gesture Wake/Sleep**

The display does not support touch-based power-saving features (e.g., waking up on touch or sleeping after inactivity), which could be inconvenient in interactive kiosk applications.

11. **No Touch Screen Customization for Specific Industries**

Unlike some specialized industrial displays, the LG 14T90N-DP does not come with pre-loaded industry-specific software (e.g., medical, retail, or logistics HMI templates). Customization is required for niche applications.

12. **No Touch Screen Support for High-Resolution Outputs**

While the display itself has a WXGA resolution, it may not support higher-resolution inputs (e.g., 4K) without scaling, which could affect image quality in some applications.

---

The **LG 14T90N-DP Gram LCD 14" Touch Display** is a **highly reliable, compact, and durable industrial touchscreen** ideal for embedded systems, automation, IoT, and HMI applications where **space, temperature resistance, and connectivity** are priorities. Its **robust build, wide temperature range, and multiple input/output options** make it suitable for factory environments, outdoor kiosks, or portable devices.

However, it is **not ideal for applications requiring high brightness, wireless connectivity, advanced touch gestures, or built-in audio**. Additionally, users may need to invest extra time in **software development, calibration, or accessory purchases** (e.g., touch protection films) to fully optimize its performance.

- You need a **compact, rugged, and low-power industrial touchscreen** for embedded or automation applications.

- Your environment has **extreme temperatures or dust/water exposure** (IP65-rated).

- You require **multiple connectivity options** (VGA, HDMI, RS-232, Ethernet, USB).

- You plan to **develop custom Linux-based HMI software** or integrate it with existing systems.

- You prioritize **longevity and reliability** over advanced touch features.

- You need **high brightness for outdoor use** (consider a display with 500 nits).

- **Wireless connectivity (Wi-Fi/Bluetooth)** is essential for your application.

- You require **pre-loaded industrial HMI software** or **advanced touch gestures**.

- **Audio output or stylus support** is necessary.

- You need **higher resolution inputs** (e.g., 4K) without scaling.

- For **higher brightness needs**, explore **LG s 15-inch outdoor-rated displays** (e.g., 15T90N).

- For **wireless connectivity**, consider **Raspberry Pi-based touchscreens** or **Allwinner H6/H9 industrial panels**.

- For **pre-loaded HMI software**, look into **Siemens, Allen-Bradley, or Beckhoff touch panels**.

- For **portable applications**, evaluate **ruggedized tablets** (e.g., Panasonic Toughbook) with touchscreens.

Details:

The keyboard was malfunctioning. Please see the pictures. Just case and complete display. The display works perfectly. The other has label remnants that will come of with cleaning, sorry I didn't have time.

One is missing the ra on case, but perfect otherwise.
