Description

Technical Field

[0001] The present invention relates to the field of panel structure manufacturing, and in particular to a panel structure for improving display effect and a manufacturing and driving method thereof. Background Art

[0002] Smartphones have been developed to the point where they can realize more and more functions. People have gradually become accustomed to using their phones for socializing, playing games, watching videos and other essential activities in daily life. At the same time, people are increasingly fond of mobile phones with large viewing angles and large screens. However, the front camera occupies a lot of screen space. In order to achieve a higher screen-to-body ratio and improve the display effect, the concept of full screen came into being. The "full screen" of full screen can be said to be our good wish, but due to various technical reasons, full screen cannot be truly full screen. Although the visual trend makes the mechanical design of automatic pop-up and push-slide cover popular, there is no doubt that the design scheme that takes into account both aesthetics and efficiency is the ultimate goal of mobile phone design. The under-screen camera is precisely a design scheme that takes into account both aesthetics and efficiency, and it seems to be about to become a trend. The current problem with the under-screen camera is that the light transmittance of the display panel above the camera module area is not good; at the same time, the "hole" of the polarizer above the camera module area causes the area above the camera module area to have a reduced contrast due to the absence of the polarizer.

DETAILED DESCRIPTION

[0053] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0054] See also Figures 1 to 18 The present embodiment provides a method for manufacturing a panel structure for improving display effect, comprising the steps of: manufacturing a pixel electrode structure having a first gate layer 011, a second gate layer 012, a gate insulating layer 020, a first active layer 031, a second active layer 032, a first source-drain electrode layer 041, a second source-drain electrode layer 042, a passivation layer 050, a flat layer 060, a transparent anode 070, and a pixel definition layer 080, wherein a light-transmitting through hole with a substrate as the bottom is provided on one side of the pixel electrode structure; and etching the pixel definition layer 080 located on the top of the pixel electrode structure to obtain the pixel electrode structure. A through hole 081; In the first specific embodiment, an electrochromic layer 090 is provided between the pixel definition layer 080 and the cathode 110, and the light transmittance of the film can be changed by controlling the voltage; Specifically, the electrochromic layer 090 is made, the electrochromic layer covers the pixel electrode structure and the light-transmitting through hole, and the electrochromic layer 090 is etched in the first through hole 081; the organic light-emitting layer 100 is evaporated in the first through hole 081, and the organic light-emitting layer 100 is connected to the anode 070 in the pixel electrode structure; the transparent cathode 110 is evaporated to form a panel structure. Please refer to Fig.13 In the second specific embodiment, the embodiment is to make an electrochromic layer 090 on the cathode 110. Specifically, the organic light-emitting layer 100 is evaporated in the first through hole 081, and the organic light-emitting layer 100 is connected to the anode 070 in the pixel electrode structure; the transparent cathode 110 is evaporated; the electrochromic layer 090 is made on the evaporated transparent cathode 110, and the electrochromic layer 090 is etched to form a second through hole 091, and the second through hole 091 is located above the organic light-emitting layer 100 to form a panel structure. It should be noted that when driving the electrochromic layer 090, a signal is input to the electrochromic layer 090 through the connection between the electrochromic layer 090 and the cathode 110; of course, in other embodiments, a driving unit that drives the electrochromic layer 090 alone can also be added for driving. It should be further explained that the RGB organic light-emitting layer 100 is evaporated in the first through hole 081, including a hole injection layer HIL, a hole transport layer HTL, an organic light-emitting layer 100EM, an electron transport layer ETL, and an electron injection layer EIL; and the transparent cathode 110 is continuously evaporated, and its material is such as magnesium-silver alloy.

When the camera needs to be called, the panel in this area does not emit light, and the driving unit does not transmit a voltage signal. At this time, the electrochromic layer 090 is in a transparent state, thereby increasing the light transmittance of this area. When the camera does not need to be called, the panel displays normally, the driving unit transmits a voltage signal, and the electrochromic layer 090 becomes opaque to reduce the influence of ambient light on the display effect, thereby increasing the panel contrast, reducing the color difference between the panel in the camera area under the screen and the panel in the normal area 140, and improving the consistency of the picture.
