Evaluation of brightness and color uniformity of LCD displays

By using a two-dimensional color brightness meter for measurement, it is possible to evaluate unevenness and other factors!

Our company conducts evaluations of brightness and color uniformity for emitting surfaces such as OLEDs, titled "Evaluation of Brightness and Color Uniformity of LCD Displays." In brightness measurement (using a two-dimensional luminance meter to measure the display surface), we compare the digital camera images of the LCD display surface with the results obtained from the luminance measurements taken with the two-dimensional luminance meter. While the distribution of uniformity is difficult to discern in the digital camera images, the color scale display of the luminance distribution highlights areas with luminance variation, making it easier to understand. 【Overview of Measurement Equipment】 ■ Measurement Items: Tristimulus Values (X, Y, Z), Chromaticity (x, y) ■ Measurement Range: 0.01 cd/m² to 1,000,000 cd/m² ■ Effective Pixel Count: 1376 × 1024 ■ Emitting Surface Size: Approximately 15 to 115 inches ■ Installation Method/Fixtures: Vertical, horizontal, etc., adaptable to shape *For more details, please refer to the PDF document or feel free to contact us.

• Analysis and prediction system

Are you struggling to explain "safety" to the client using just drawings? • The risks in blind spots are difficult to convey to the client through drawings alone. • Safety measures often become a target for cost reduction, making it hard to communicate their necessity. • There is a concern that the client might say, "It's more dangerous than I thought," after completion. Risks that are clear to design professionals are not easily understood intuitively by clients who are outside the field. This document is not just a simple explanation of sensor functions; it is a guide to visually explain "why sensors are necessary in those locations." It can be used directly as explanatory material for clients. Here are three key points for utilizing this document: 1. Visualization of Risks Blind spots during departure and contact risks within the site are illustrated clearly. 2. Clarification of Selection Criteria A comparison table outlines the differences between complex sensor types such as infrared, ultrasonic, and loop coils. 3. Diagram of System Configuration It illustrates not just the sensors alone, but how they are combined with rotating lights and control panels, providing practical assistance for electrical equipment design. Please make use of this to prevent "rework after completion" and "accident risks."

In facilities operating nurse call systems, we have made bed exit sensors wireless, allowing them to notify in conjunction with the nurse call system. By simply connecting the mat sensor "Foldable Thin Matt-kun," the body movement call "Ugo-kun," and the wheelchair body movement call "Ayumi-chan" to the transmitter HB-RS, you can make the bed exit sensor wireless. The infrared sensor "Just Place Pole-kun" has the transmitter HB-RS built-in. This helps prevent accidents caused by falls, slips, or wandering, contributing to the efficiency of medical operations. 【Features】 ○ Wireless conversion by simply connecting existing sensors to the transmitter HB-WSK. ○ Bed exit sensors notify wirelessly in conjunction with the nurse call system. ○ Up to 5 transmitters can be registered with one receiver. ○ The communication distance between the transmitter and receiver is approximately 10 meters. ◎ For more details, please contact us or download the catalog.

We will introduce the implementation results of the sensor technology developed by the Hotron Group, which has been cultivated over more than half a century, through customer case studies. In addition to automatic door sensors, we also offer a wide range of vehicle detection sensors and nursing/care sensors. We have many implementation examples available, so please take a look at the case study page.

Full and empty management refers to the real-time display of parking availability and the management of efficient use of parking spaces. By utilizing Hotron's sensors, drivers can quickly discover available parking spaces, achieving efficient parking lot operations. ■ For large parking lots, the "floor management method" and "block management method," which focus on cost reduction, are recommended. Sensors are installed at regular intervals to count the number of vehicles passing through. This method offers the advantage of easy installation and low costs. 【Target Products】 - Vehicle Count Sensor CCS2 - Ultrasonic Sensor HM-UX2/UW2 ■ For smaller scale operations, the "space management method," which installs sensors in each parking space to display availability with high accuracy, is recommended. By ensuring accurate full and empty displays, it helps prevent unnecessary entry of new vehicles and enables safe parking lot operations. 【Target Products】 - Occupancy Detection Sensor HM-UX2/UW2 - Occupancy/Pass Detection Sensor HM-LC6 - Occupancy Detection Sensor HM-LC7/LC7-FLS - Occupancy/Pass Detection Sensor HM-S6 - Occupancy Detection Sensor HM-S8

We will be exhibiting at the "JECA FAIR 2026 - 74th Electrical Industry Exhibition." Our company, a 110-year-old electrical materials manufacturer, operates under the motto "Turning desires into reality," providing various electrical materials and metal processing products. At our exhibition booth, you will be able to see not only pull boxes but also actual products such as conduit accessories, ducts, and supports. Additionally, we will hold seminars several times a day on strength calculations and seismic calculations. If you have concerns about whether your material selection is optimal, if the pricing is appropriate, or if it takes too long to receive calculation documents, please feel free to consult with us at our booth (3-39). Our experienced design staff will be available to speak with you directly! 【Main Exhibits】 ■ Seismic supports ■ Metal ducts ■ Accessories for conduits ■ Accessories for flexible conduits ■ Pull boxes ■ Support materials 【Exhibition Information】 Date: May 27 (Wednesday) - May 29 (Friday), 2026 Venue: Tokyo Big Sight, Halls 1, 2, 3, and 8
