Sensor applications of thin‐film devices originating in display technologies

Abstract

Thin‐film devices are widely utilized for flat‐panel displays, and the essential advantages of the thin‐film devices are generally large‐area production, various‐material substrate, layered structure, etc. Appropriate applications are flat‐panel displays, and other applications where the abovementioned advantages are available and the disadvantages are acceptable are sensor applications. Moreover, if the sensor devices can be made by thin‐film devices that have been already utilized for flat‐panel displays, they can be made without additional cost. Therefore, thin‐film devices are again promising for sensor applications especially for interactive displays. We are investigating sensor applications of thin‐film devices. Particular in this journal paper, we review sensor applications of thin‐film devices originating in display technologies. The various sensors are visible‐light sensor, infrared‐light sensor, temperature sensor, magnetic‐field sensor, etc. Many research results from many research organizations as well as our research laboratory are introduced.

Toward Intelligent Display with Neuromorphic Technology

“…[17][18][19] The physical separation of the sensing module and other modules leads to large energy consumption and significant delay in data transformation, resulting in difficult frequent data interaction. [20][21][22] Correspondingly, to pursue more realistic display effects, traditional display technology focuses on improving the color brightness and purity of light-emitting pixels, [23] reducing pixel size, [24] fabricating large-scale complex array circuits, [25,26] and designing more complex driving circuits. [27] However, traditional display technology essentially adopts the storage-compute separation strategy.…”

In-situ optimization of lateral film uniformity in PVD system by using Fiber Bragg grating temperature sensors

“…PVD techniques (Physical Vapor deposition) form an important class of techniques which are widely explored for the preparation of technologically important optical and electronic devices including optical filters [1], high reflecting (HR) mirrors [2], photovoltaics [3], display, sensors [4] etc In almost every such application one common concern is the spatial uniformity in terms of thickness and physical attributes of the film deposited in different lateral spots of the substrate. This gains increasing attention, as the batch production and large area manufacturing of thin film devices becomes necessary to fulfill the criteria of cost reduction.…”
