This invention belongs to the field of energy measurement in gas transmission and distribution systems, specifically involving a technology based on organic light-emitting diode display.ITRON Electronic Correction InstrumentIn recent years, due to the rapid development of the gas industry, more and more ITRON electronic correction instruments are used in conjunction with primary gas flow measurement instruments for gas measurement. The ITRON correction instrument measures the flow, temperature, and pressure signals of fluids, using preset algorithms through a microprocessor system to obtain the reference state flow and total amount of the fluid, recording data and outputting it to a display for on-site observation.

Currently, the ITRON electronic correction instrument is installed in industrial environments, with the power supply mostly provided by batteries, and the display part using LCD technology. The liquid crystal display is a type of monitor that uses liquid crystal control light transmission technology. Due to the limitations of materials such as liquid crystals and polarizers, it operates poorly below 0 degrees, has a slow response time, and may fail or have no display; at high temperatures, the liquid crystal can change color, easily causing permanent damage to the internal liquid crystal molecules, resulting in a blackened display that cannot be restored; due to the display principle of LCDs, the viewing angle of the LCD screen is not ideal, with a narrow viewing angle. This display method narrows the working temperature range and visibility range of the ITRON electronic correction instrument, greatly affectingITRON Electronic Correction Instrumentits applicable locations and increasing subsequent maintenance costs.

To overcome the above technical defects, technicians have provided an ITRON electronic correction instrument based on organic light-emitting diode display technology. An ITRON electronic correction instrument based on organic light-emitting diode display technology includes a shell, where the shell consists of a bottom shell and an openable outer shell, with an antenna at the upper end of the shell, a power supply inside the bottom shell, a control circuit board inside the shell, and an organic light-emitting diode display outside the shell, which is embedded in the shell and electrically connected to the control circuit board through a flexible connector. One end of the shell is hinged to the bottom shell, and the other end is openable; the shell is recessed inward to form a groove, with the power supply placed inside the groove; the groove protrudes outward in the circumferential direction to form a sealing strip, and the shell has a corresponding sealing groove that fits with the sealing strip, forming a sealed fit; the opening end of the shell and the bottom shell are fixedly connected by screws; a fixed lead seal is set at the screw fixing position; the antenna is foldably set at the upper end of the shell; the antenna includes a fixed end and an antenna end, with the fixed end fixedly set at the upper end of the shell; the bottom of the antenna end has a U-shaped groove hinged to the fixed end; the power supply is a lithium battery.

The advantages of the above utility model are: applying the organic light-emitting diode display toITRON Electronic Correction Instrumentexpand the working temperature range and visibility range of the ITRON correction instrument, shorten the response time when displaying data, reduce the power consumption of the ITRON correction instrument, and lower subsequent maintenance costs.
