Flat Panel Display Tester Model 27015 | Chroma ATE

The following specifications are preliminary and subject to change without notice.

The tester’s multi-modular support reduces production costs, ensures long-term viability, and allows you to select the optimal solution for any given test scenario.

The 27015 features a dual-slot design that allows for the simultaneous testing of multiple different DUTs. It supports multiple signal outputs, including MIPI, eDP, and LVDS signal modules, providing users with a range of signal testing applications to fully meet the needs of automotive panels of various sizes.

Equipped with a high-speed independent graphics core, the Chroma 27015 boasts significantly improved graphics and data transmission speed. With an ultra-high resolution image switching time of just 0.1 seconds (assuming a 4K bitmap), it offers greatly enhanced testing efficiency.

The 27015's main unit can support two high-speed graphics processors. This allows it to simultaneously output different resolutions, test patterns, and power for two signal modules, enabling simultaneous testing of multiple different panel sizes.

The 27015 has 4 programmable DC power supplies with a maximum output current of up to 150W (VBL) / 45W (VDD), with a maximum voltage and current of 55V / 15V and 10A / 3A, respectively. With the FPD Master software, the voltage can be adjusted in 0.01V increments, providing stable and continuous DC voltage output. This allows users to customize the power supply for their specific applications, fully satisfying the power requirements of a wide range of TVs and monitors.

The instrument provides a power source, signal, individual pin activation, and timing editing in increments as small as 1ms. The timings of power, signal, pin output, and shutdown can all be fine-tuned to user requirements.

Chroma 27015 provides OVP (Over Voltage Protection), OCP (Over Current Protection), UVP (Under Voltage Protection), and UCP (Under Current Protection). You can set your own protection parameters; if the current or voltage of the DUT is detected to exceed the set value during the output process, the protection mechanism will be activated immediately to avoid product damage.

The Protection Time Delay function ensures test accuracy by preventing the inrush current generated by the DUT’s power supply from triggering the protection mechanism.

When conducting a series of tests, test accuracy is often affected by voltage drops in the power transmission caused by cables, connectors, and distance. To mitigate this, the instrument is equipped with a Remote Sense function that can automatically adjust the output to harmonize the difference between the actual test voltage and the set voltage.

The Chroma 27015 Flat Panel Display Tester is equipped with an embedded multimedia card (eMMC) that can store anywhere from 341 to 1365 BMP image files, depending on the image resolution, with a maximum resolution of 8K. In addition to using the built-in images, users can also add their own test images to meet a variety of testing needs.

*Depending on module resolution

The FPD Master software supports different configurations for different signal modules, including eDP, MIPI, and LVDS. When you select the module of your choice, the corresponding parameters are displayed in real-time. Each module can store up to 100 configurations.

When pairing the 27015 Flat Panel Display Tester with the 71241 High Accuracy Universal Measurement Probe or the 71242 Small-Size Measurement Probe, you can use the GO/NOGO software to optimally adjust the Auto Flicker test steps(FMA<3%) in less than 5 seconds.

*Requires adjustment data (PMIC) and panel setting

Chroma provides a complete (full line / single station) modular solution for automated LCD testing. The 27015’s small form factor makes it suitable for space-conscious production line designs. Through expert technical consultation, continuous software development and comprehensive technical support, we can help you find the production and R&D test applications that best suit your needs.

The display lights on the 27015 Flat Panel Display Tester offer users a quick and easy way to understand the tester's status and confirm the DUT's and testing status in real-time.

The FPD Master software comes with a Timing Wizard feature that allows users to set standard timing parameters or define their own horizontal and vertical timing parameters. The software can automatically calculate the pixel rate, set the color depth, and adjust the Hsync and Vsync polarity of the display to meet a wide range of testing needs.

*Requires adjustment data (PMIC) and panel setting

During production, display panels can develop significant pixel defects as well as bright or dark spots brought on by contaminants like dust, scratches, and other impurities. The 27015 combines GO/NOGO software with the Cursor Position function, which allows you to pinpoint the exact physical coordinates of single pixels/dots and RGB color vector coordinates on the DUT's own display, and record the corresponding data for laser repair machine positioning and restoration.

The FPD Master software comes equipped with 9 types of test patterns, including Bitmap, Color Bar, Gray Scale, Outer Frame, CABC, Character, Horizontal Stripe, Check Board, and Multi Pixel. You can combine and edit the presentation and color of each test pattern to create a wide variety of images for testing.

The Chroma 27015 main unit has pre-installed 4K and Full-HD files for resolution, RGB, contrast correction, algorithm verification, True Color change, panel convergence, and other output tests, providing a wide range of test charts.

The 27015 can be used with the A040206 Remote Controller, which provides an on/off button for signal and power, a control knob for quick switching between functions and grayscale gradient adjustment, and real-time voltage/current display on a 20x4 LCD screen. (optional)

The 27015 FPD Tester can be supplemented with the 67394 Multi-Channel Power Supply Module to meet various voltage requirements for small to medium size panels. The multiple outputs can be combined with signal and timing control, and the timing can be edited in 1ms increments to suit a variety of production test applications. (optional)

Applications: panel manufacturers, driver IC design, repair centers, PCB substrate testing, automatic testing equipment manufacturers, IC reliability testing, demonstration, product verification, etc.
