Description

Electronic equipment, display device, display panel and preparation method thereof

Technical Field

The invention relates to the technical field of electronic equipment display module structures and preparation methods thereof, in particular to electronic equipment, a display device, a display panel and a preparation method thereof.

Background

At present, the trace area 12 on the panel 11 (display panel) and the area where the display panel is connected to the middle frame are covered by the ink layer 14 printed on the CG 13(Cover Glass, protective plate for protecting the display module). Referring to fig. 1 and 2 together, fig. 1 is a schematic partial structure diagram of an edge position of an electronic device in the conventional art; fig. 2 is a schematic diagram of a partial structure of a hole punched in the middle of a display screen of an electronic device in the prior art.

Because the conventional technology is that the silk-screen printing ink layer 14 is on the CG 13, the color of the ink layer is difficult to make into a gradient, and meanwhile, because the silk-screen printing ink layer 14 and the display Area (i.e., AA Area, active Area effective display Area) of the display panel need to avoid about 0.3mm (tolerance G of silk-screen printing of the ink layer, 15 in the figure is indicated as AA Area of the display panel 11), a visible Area (View Area, visible Area, that is, a black edge Area that can be seen after installation) of about 0.3mm exists, the visible Area is black, if the silk-screen printing ink layer is blue or other colors, a very obvious color difference exists between the silk-screen printing ink layer and the display panel, and the overall appearance expressive force of the electronic device is affected.

In the scheme in fig. 2, since the single-side width T1 Of the FOV (Field angle) from the edge Of the trace area 12 is generally about 0.59mm (too wide may cause the opening to occupy too much screen occupation ratio), the width T2 Of the screen printing area (the screen printing ink layer 14) from the AA area 15 is generally 0.25mm, and the width T3 Of the screen printing ink layer 14 from the FOV needs 0.25mm, the width T4 Of the screen printing ink layer 14 in the conventional art is only T4-T1-T2-T3-0.59-0.25-0.09 mm, and the screen printing area with such a small size cannot be manufactured in the current process.
