Detailed Description

In order to make the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions of the present utility model will be clearly and completely described below with reference to specific embodiments of the present utility model and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1

As shown in fig. 1 to 3, the vehicle-mounted display panel provided by the present utility model includes:

a first polarizer 10; an array substrate 20 covering the first polarizer 10; a second polarizer 30 covering the array substrate 20; a glue layer 40 at least partially covering the second polarizer 30; an optical film cover plate 50 covers the adhesive layer 40.

The utility model uses the optical film as the cover plate, omits the use of a glass cover plate, reduces the production cost, improves the production efficiency and improves the market competitiveness, the optical film cover plate 50 can be composed of one or more layers of optical films, and the optical film has wide optional range and can also have various performances of the glass cover plate.

The array substrate 20 includes a display region and a non-display region disposed at the outer periphery of the display region.

The optical film cover 50 screen prints the ink layer 60 in an area other than the corresponding display area. As a rim portion.

The size of the optical film cover plate 50 is preferably not smaller than the size of the array substrate 20. Since the optical film cover 50 is required to function as a protection for the display panel, the display panel can be better protected by being sized more.

The array substrate 20 includes a first substrate, a liquid crystal layer, and a second substrate stacked.

The optical film cover 50 includes one or more optical films. One or more functional optical films may be selected, the substrate of the optical film comprising PET, PC, TAC; the functions of the optical film include anti-glare, anti-reflection, anti-fingerprint, retardation, and increase in surface hardness, so that the optical film cover 5 can also have various properties of a glass cover.

In this embodiment, the vehicle-mounted display panel is a large-sized display panel, and because the non-display area is only used as a frame, the non-display area can be designed as narrow as possible, and the screen occupation ratio is increased.

Example 2

As shown in fig. 4 and 5, unlike embodiment 1, at least one icon 70 is further provided in the non-display area in this embodiment. Thus, the ink layer 60 of the optical film cover 50 in the non-display area is also screen printed with at least one icon 70. Meets the display and beautiful requirements of instruments and meters.

In this embodiment, the optical film cover 50 is preferably silk-screened with a plurality of icons 70 on the non-display areas on the left and right sides. In particular, icons 60 are evenly distributed on both sides of the non-display area, and the overall appearance is more attractive.

The vehicle-mounted display panel in this embodiment is a small-sized display panel, and since the icons 70 are provided on the non-display area, a frame having a width not smaller than the width of the icons 70 needs to be reserved when the screen printing ink layer 60. The area of the non-display area will be relatively large and the bezel will be wide.

Example 3
