Under the current economic situation, China’s economy is steadily moving from the stage of high-speed growth to that of high-quality development. while climate risks arising from global warming are receiving increasing media attention. Media attention has a profound impact on the perception and investment decisions of financial market participants. This paper constructs a climate risk index based on media attention and empirically investigates its relationship with stock volatility. It is found that the climate risk media index significantly affects stock volatility, which provides a theoretical basis for the regulation of financial asset price volatility. Through in-depth study of its influence mechanism, it can provide accurate decision support and risk management strategies for financial market stabilization.

A novel LTPS‐based compensation circuit is adopted to reduce the power consumption, which is reduced by 16.63% due to the special design is set to reduce the source‐drain voltage (Vds) of the DTFT. Furthermore, some signals are simultaneously set for the entire panel to eliminate color shift and screen tearing problems. The novel circuit is suitable for MLED splicing display products which have less power consumption and can generate high‐quality images with excellent gamma curves. [ABSTRACT FROM AUTHOR]

The COG light board is prone to breakage during the stringent mechanical testing, which is a major pain point for COG light boards. In order to improve the adaptability to the back cover which is made by stamping, the elastic supporter solution is proposed and its feasibility is confirmed by the FEM simulation method and a series of tests. The pain point is solved successfully. [ABSTRACT FROM AUTHOR]

The authors systematically reviewed peer-reviewed studies done with LENA (Language ENvironment Analysis) technology, guided by three research questions: (a) What types of studies have been conducted, and with which populations, since the launch of LENA technology?; (b) What challenges related to use of LENA technology were identified?; and (c) What are the implications for practice and future research using LENA technology? Electronic databases, the LENA Research Foundation website, and bibliographies of already-included studies were searched; 38 studies were identified. The authors selected studies on the basis of purpose, design, participant characteristics, application of LENA technology, and results. They found that LENA technology was used with a range of populations to yield a variety of information. Though challenges and limitations are associated with LENA technology, great potential exists for further research and a resultant increase in evidence-based understanding of early language development and interventions on its behalf.

When viewing the Mini LED display screen from a large angle, the color seam appearing at the edge of the module can disrupt the uniformity of the entire screen's bright state. This paper studies the formation mechanism of color seam and solves the problem by optimizing the packaging film structure. [ABSTRACT FROM AUTHOR]

The use of high‐power circuit devices puts forward high heat dissipation requirements for LED display. Several heat dissipation methods are studied in this paper to provide a reasonable idea of high power consumption LED display. [ABSTRACT FROM AUTHOR]

This paper mainly introduces the dot technology, which is printing or spraying high‐reflectivity materials directly above the LED, resulting in a reduction of half the number of partitions, a decrease in the number of optical film materials by 2~4 sheets, a reduction in module thickness by 0.5mm, and an overall cost reduction of approximately 30%. The dot can be a simple circle or a variety of pattern types (octagonal star, hex star, etc.) [ABSTRACT FROM AUTHOR]
