Light source module and method for manufacturing the same, and backlight module and display device using the same
A light source module and a method for manufacturing the same, and a backlight module and a display device using the same are provided. The method includes the following steps. A reference light source module is provided. The reference light source module comprises a substrate and plural light-emitting units arranged on the substrate. Then, plural optical trends between every two adjacent light-emitting units are obtained. Then, plural optical ratios between every two adjacent light-emitting units are calculated, in which each of the optical ratios is a ratio of each of the optical trends to a total reference optical trend of the reference light source module. Then, plural target distances are calculated according to the optical ratios and plural initial distances between every two adjacent light-emitting units are adjusted according to the target distances, thereby forming a target light source module.
DISPLAY PANEL AND DISPLAY MODULE
The present invention provides a display panel and a display module. The display panel includes a first substrate, a first electrode layer, a light control layer, a second electrode layer, and a second substrate. The light control layer includes a first liquid crystal and light blocking layers. When no voltage is applied to the light control layer, the first liquid crystal is configured as an atomized liquid crystal for scattering light. When a voltage is applied to the light control layer, the first liquid crystal is configured as a transparent liquid crystal, thereby effectively improving an anti-peep performance of the display panel.
Backlight unit and liquid crystal display including the same
A liquid crystal display includes a liquid crystal display panel, a backlight and a cover. The backlight includes optical sheets that are configured to be mounted to the cover using a plurality of holes provided on the optical sheet that material to corresponding protrusions provided on the cover. The holes and protrusions are configured to reduce damage or misalignment to the optical sheet that may be caused by heat generated inside the liquid crystal display.
