P‐178: Improve the response time of LCD and expand applications at low temperature

With the requirements for applications in extremely cold environments, LCD (Liquid Crystal Display) technology, limited by the properties of liquid crystal materials, exhibits poor image quality, especially when displaying rapidly changing images at low temperatures. Therefore, improving the response time at low temperatures is a key issue. In this paper, we have designed a heating circuit for the LCD. This circuit is controlled by an internal sensor, which improves the LCD's performance at low temperatures. Experimental results show that the internal sensor can provide feedback within a range of ‐50℃ to 150℃. The Gray‐ to‐Gray (GtoG) response time can reach 100ms at ‐40℃, greatly enhancing the competitiveness of LCD technology.
