چگونه برداشت های افراد از مورا ارزش بازار LCD را تحت تاثیر قرار می دهد؟

Liquid crystal displays (LCDs) hold a large share of the flat-panel display market because LCDs offer advantages such as low power consumption, low radiation, and good image quality. However, image defects, such as spotlight, uniformity, and Mura defects, can impair the quality of an LCD. This research examined human perceptions of region-Mura and used Response Time and subjective markdown price to indicate the various severity levels of region-Mura that appeared at different display locations.

Thin-film transistor liquid crystal displays (TFT-LCDs) have the largest share in the flat-panel display (FPD) market [10]. LCDs deliver full-color display capabilities, low power consumption, low radiation, and low weight, but some LCDs have noticeably non-uniform brightness problems, called Mura. Mura are imperfections of a pixel matrix surface that are typically larger than a single pixel, and that are visible when the display screen is driven to a constant gray level [21] and [23]. Various physical factors, such as non-uniformly distributed liquid crystal material and foreign particles within the liquid crystal, produce Mura in LCDs. Depending on their shapes and sizes, Mura defects may be classified as spot-Mura, line-Mura, and region-Mura defects [8], as shown in Fig. 1.

This study has investigated the influences of Mura Distance and Quadrant on human perception in terms of three dependent variables: Response Time, Decision Time, and Markdown. The results indicate that the effect of Mura Distance is highly significant to the measurements of Response Time, Decision Time, and Markdown (p < 0.01). The interaction between Mura Distance, Mura Level, and Quadrant is also significant for Response Time and Markdown (p < 0.01). These results imply that, for Mura of levels 1.76–4.72, Mura Distance has a significant effect on human perceptions of the display and on perceptions of a fair price markdown.
