AI Technical Summary
Technical Problem
In existing technologies, the circular shape of the light spot of LED chips causes dark spots and halos when setting up LED chip arrays, resulting in uneven image quality.
Method used
A reflective sheet composed of reflective cups is used. The reflective cups include a base plate, a shielding cover plate, and an annular sidewall, forming a rectangular light outlet for reflecting and forming a square light spot, which is adapted to the square pixel partition of the LCD panel.
Benefits of technology
By forming square light spots, the display quality is improved, halo effect is avoided, and a high-contrast, high-fidelity display effect is achieved.

Abstract
本发明公开了一种反射片、背光模组和显示装置，反射片由若干个阵列设置的反射碗杯组成；反射碗杯包括底板、遮挡盖板和环形侧壁，底板的中心位置设有装配口；遮挡盖板与底板平行设置，正对装配口；遮挡盖板的侧面延伸出连接条，连接条朝向装配口弯折且与底板连接；遮挡盖板、连接条和底板组合成装配槽，装配槽用于盖合背光模组的发光件；环形侧壁与底板连接；环形侧壁围绕底板的外边缘设置，形成包围遮挡盖板且呈喇叭状的出光通道；并且，环形侧壁背离底板的一端形成出光口，出光口的形状为矩形。发光件的正面被遮挡，光线只能侧向射出到底板和环形侧壁上，最终反射至出光口，形成矩形光斑，以适配矩形分区的像素，解决光晕问题。
