— In order to have drinking water, some countries have to use chlorine. It is use cause is effective and it's cheap. An alternative to this process is the UV disinfection of drinking water. Most of the devices in the market use UV bulbs or mercury lamps. The UV LED, which is cheaper and smaller, allows creating new smaller devices. The main contribution of this paper is the use of Genetic Algor...

Under‐display camera (UDC) allows viewers to interact with the and watch display at same time. This paper introduces UDC for Mini‐LED/Micro‐LED displays embedding by drilling a pinhole between LED dies. Based on such an application, main issues of images are low‐light noise. We propose CNN‐based image restoration approach enhance brightness remove Moreover, input proposed neural network uses th...

LED lighting has the potential to offer many benefits to the user and to society as a whole. Very high efficiency together with extremely long life expectancy of the LEDs reduces the energy consumption and the use of resources, and can offer low lifecycle cost. In order to become widely accepted, LED lighting must provide dimming capability at least equivalent to that offered by traditional inc...

According to the measurement, luminescence of micro‐LED has great divergence. The luminous intensity is uniform when less than 45 degrees, but there still strong at more 60 degrees. large scattering angle makes light easily crosstalk with adjacent units, which affects display effect and reduces efficiency. In this paper, a variety surface microstructures are introduced, corresponding micro‐lens...

Many techniques and algorithm have been developed to solve the problem of text extracted from natural scenes. Text extraction is emerging and challenging era in the computer vision. Text which is embedded into the image contains semantic information which is used in many other applications such as information retrieval of complex images, robot navigation, useful for visually impaired persons, s...

A real-time full-color phase-only holographic display system generates holograms of 3D objects. The system includes a 3D object formed by voxels, an internet-based transmission capability that transmits the object information to the server, a real-time hologram generation unit, and a holographic display unit with incoherent illumination. The server calculates three phase holograms for RGB compo...

In this paper we show how light emitting diodes (LEDs) can be used in conjunction with existing display technologies as a means for achieving ultra-rapid visual stimulus exposure durations. We review existing rapid visual display methods, and show how our apparatus overcomes the limitations inherent with each technique. Our apparatus, the LED tachistoscope, takes advantage of the fast-switching...
