A mapis matrix has been integrated in the back plane of flexible AMOLED to form a high performance light path for the fingerprint sensor. Mapis fingerprint shows reasonable optical image properties and reliabilities.

A mapis matrix has been integrated in the back plane of flexible AMOLED to form a high performance light path for the fingerprint sensor. GOP technology is applied to make the fingerprint unit as lower as possible in the cell phone. GOP IC's bump should be distributed uniformly for mechanical strain.

In quantum dot color filter (QDCF) LCD blue backlight is converted to red/green light separately by red/green quantum dot materials. In cell polarizer is necessary due to the depolarization of quantum dot material. WGP is more promising as in cell polarizer. Therefore it is particularly important to insure the transmittance of blue light as high as possible. In the article, the stacks of WGP and the upper and lower layers were designed to improve the transmittance of blue light. WGP with the upper and lower layers by chemical vapor deposition was fabricated by using nano-imprinting lithography. The blue light transmittance of WGP in the panel without the upper and lower layers was about 24%. We optimized the design of thin film without changing the structure of WGP to make the transmittance to be increased to 40%. Experimental results showed that the proposed design could achieve a fairly high transmittance 39%.

The low power consumption of RLCDs has significant advantages over traditional display solutions, making it a competitive candidate for next‐generation green displays. However, in some cases, improper design may cause the RLCD to turn yellowish, causing display distortion. To solve this, we proposed a series of methods to solve such color cast problems. In this paper, the reflectance associated with the phase state between the circular polarizer and the liquid crystal has been adjusted by liquid crystal to decrease this color cast. By redesigning the liquid crystal parameters, the color deviation has been successfully improved. Finally, the samples produced on production lines verified that the Improvement Scheme did make the yellowish panel whiter.
