Touch screen apparatus with light sensor arrays and obstacles
The patent US12032793B2 describes a touch screen (TS) apparatus designed to enhance touch detection accuracy through a sophisticated arrangement of sensor arrays and physical obstacles. The apparatus features a display surrounded by a frame with four edges, where at least two sensor arrays are positioned on opposing edges. Each sensor array consists of multiple light transmitters and light sensors, which are aligned to create direct light paths between them. The innovation lies in the inclusion of physical obstacles, such as thin opaque guards and optical filters, strategically placed on the frame's edges to minimize stray light interference. This configuration allows the system to detect touch events by identifying when a direct light path is blocked, thus determining the location of the touch based on the specific path that is obstructed.
Additionally, the patent outlines various configurations and methods for optimizing the touch detection process. The sensor arrays can be organized in repeating groups, and the light transmitters can be powered sequentially to transmit bursts of light pulses. The design also accommodates a rectangular display divided into two halves, with multiple sensor arrays positioned around the edges to ensure comprehensive coverage. The method for detecting touch events involves a systematic activation of the light transmitters and subsequent analysis of blocked paths to pinpoint the touch location. This innovative approach aims to improve the performance of touch screens, particularly in environments with varying light conditions, by effectively managing light transmission and reception.
