As shown in fig. 1 and 2, an embodiment of the present invention provides a Liquid Crystal Display (LCD) panel 1000.
As shown in fig. 1, the liquid crystal display panel 1000 includes a light-transmitting display area DA1, a normal display area DA2, and a non-display area NDA. The light-transmitting display area DA1 and the normal display area DA2 may be areas for setting sub-pixels for displaying images. The transparent display area DA1 may be located at an upper portion of the liquid crystal display panel 1000 or may be located at a middle portion of the liquid crystal display panel 1000, and the number of the transparent display areas DA1 may be one or more, and may be specifically determined according to needs. The normal display area DA2 is located at least one side of the light-transmitting display area DA1 to at least partially surround the light-transmitting display area DA1. The light-transmitting display area DA1 has both light-transmitting and display functions, and the light-transmitting display area DA1 has a light transmittance that is greater than that of the normal display area DA2, for example. External light can pass through the light-transmitting display area DA1 to reach the back side of the lcd panel 1000, so that an lcd panel having both an under-screen display and an optical function such as photographing can be designed to increase the screen ratio. The non-display area NDA may be a region for setting a driving unit such as a gate driving circuit for providing a driving signal to a pixel driving circuit of a sub-pixel, and for setting some wirings for providing signals to the driving unit. Within the non-display area NDA, no subpixels for display are typically provided. The non-display area NDA may be disposed on at least one side of the light-transmitting display area DA1 and the normal display area DA2 to at least partially surround the light-transmitting display area DA1 and the normal display area DA2.
Referring to fig. 2, the lcd panel 1000 includes two polarizers, a first substrate 3, a second substrate 4, a liquid crystal layer 5, and a phase compensation layer 6.
The two polarizers are oppositely arranged and comprise an upper polarizer 1 and a lower polarizer 2 with opposite polarization directions. The lower polarizer 2 is used for converting natural light emitted by the backlight module into linear polarized light, and the upper polarizer 1 is used for transmitting or blocking light passing through the liquid crystal layer 5 and the lower polarizer 2.
Referring to fig. 3, the first substrate 3, i.e. the array substrate, is located between the lower polarizer 2 and the upper polarizer 1. The first substrate 3 includes a substrate 30, a thin film transistor layer 31, a first passivation layer 36, a color resist layer 37, a second passivation layer 38, and a pixel electrode layer (not shown).
The thin film transistor layer 31 is located above the substrate 30 and includes an active layer 310, a gate layer 311, a source-drain layer 312, and an insulating layer 315 located between the active layer 310 and the gate layer 311. The active layer 310 includes a plurality of active patterns, the gate layer 311 includes a plurality of gate patterns, and the source drain layer 312 includes a plurality of sources and a plurality of drains. The plurality of active patterns, the plurality of gate patterns, and the plurality of sources and the plurality of drains collectively form a plurality of thin film transistors 319 to form a plurality of pixel driving circuits.
The first passivation layer 36 is disposed on the thin film transistor layer 31 for protecting the plurality of thin film transistors 319.
The color resist layer 37 is disposed on the first passivation layer 36 and includes a plurality of color resists for realizing color display.
The second passivation layer 38 is located on the color resist layer 37 and is used for protecting a plurality of color resists.
Referring to fig. 4, the pixel electrode layer is disposed on the second passivation layer 38 and includes a plurality of pixel electrodes 39. Each pixel electrode 39 is electrically connected to the thin film transistor 319 of the corresponding pixel driving circuit, so as to realize active control of the pixel voltage loaded on the pixel electrode 39. Each of the pixel electrodes 39 includes a plurality of first slits 391a (first slit) extending in a first direction and a plurality of second slits 391b (second slits) extending in a second direction, the first direction and the second direction intersecting each other, and the first direction and the second direction intersecting a row direction or a column direction of the liquid crystal display panel 1000. Illustratively, the first direction is at an angle of 45 ° to the row direction and the second direction is at an angle of 135 ° to the row direction. The pixel electrode 39 is substantially rectangular, and may be made of ITO (Indium Tin Oxide).
Referring to fig. 3 and 4, the phase compensation layer 6 is located between the second passivation layer 38 and the pixel electrode 39, and includes a plurality of phase compensation patterns 60. Wherein, the orthographic projection of each phase compensation pattern 60 on the corresponding pixel electrode 39 overlaps with the plurality of first slits 391a and the corresponding color resistors. The material of the phase compensation layer 6 includes one of silicon nitride (SiNx), silicon oxide (SiOx), a stack of silicon nitride and silicon oxide. The plurality of phase compensation patterns 60 may be formed by patterning the phase compensation layer 6 through a photolithography and etching process.
Referring to fig. 2, the second substrate 4 is disposed on the first substrate 3 and between the two polarizers. The second substrate 4 includes a common electrode for generating an electric field with the plurality of pixel electrodes 39 to drive liquid crystal molecules of the liquid crystal layer 5.
The liquid crystal layer 5 is located between the first substrate 3 and the second substrate 4 to deflect the light passing through the lower polarizer 2. The liquid crystal layer 5 may be a VA (vertical alignment), vertical Alignment type liquid crystal.
Referring to fig. 4, the display portion of the lcd panel 1000 may be seen as being formed of a plurality of sub-pixels (i.e., a plurality of light emitting points) from a top view, so we refer to the pixel electrode 39, the pixel driving circuit electrically connected to the pixel electrode 39, a portion of the common electrode corresponding to the pixel electrode 39, a portion of the liquid crystal layer 5 driven by the pixel electrode 39 and a portion of the common electrode, and the color resist corresponding to the pixel electrode 39 as sub-pixels. It should be noted that, the partial common electrodes of the plurality of sub-pixels are electrically connected to each other to form a whole common electrode, and a part of the liquid crystal layer 5 of the plurality of sub-pixels forms the whole liquid crystal layer 5, and the liquid crystal layer 5 has a certain fluidity. For convenience of distinction, a plurality of the sub-pixels located in the light-transmitting display area DA1 are referred to as a plurality of first sub-pixels 8, and a plurality of the sub-pixels located in the normal display area DA2 are referred to as a plurality of second sub-pixels 9. The arrangement of the plurality of second sub-pixels 9 is the same as the arrangement of the plurality of first sub-pixels 8.
Each of the first sub-pixels 8 includes two first domains 81 (first domains) and two second domains 82 (second domains), each of the first domains 81 and the corresponding second domains 82 being adjacently arranged in the column direction, each of the first domains 81 and the corresponding second domains 82 being adjacently arranged in the row direction. The first slits 391a of each pixel electrode 39 are located in the corresponding first domain 81, and the second slits 391b of the pixel electrode 39 are located in the corresponding second domain 82. And, the orthographic projection of each two of the phase compensation patterns 60 on the corresponding pixel electrode 39 is located in two of the first domains 81.
In the prior art, the sub-pixel is generally designed to have a 4-domain (i.e. two first domains 81 and two second domains 82) structure, and after power-up, the liquid crystal is inverted to an angle of 45 ° with respect to the lower polarizer 2. As can be seen from the transmittance formula, the liquid crystals of adjacent domains inside one first sub-pixel 8 have a phase difference of pi. According to the diffraction formula:
where d/(w+d) denotes the grating duty cycle, φ denotes the adjacent region phase difference, m denotes the diffraction order, η denotes the diffraction efficiency.
It is found that the diffraction efficiency reaches the maximum value and the diffraction effect is the most serious. The light is bent after passing through the liquid crystal display panel, and thus the blurring phenomenon is serious. However, in this embodiment, by designing the phase compensation pattern 60 overlapping with the plurality of first slits 391a and the corresponding color resistors in the first domain 81, a periodic phase difference structure is introduced into the panel to perform phase compensation, so as to offset the phase difference caused by the periodic distribution of the liquid crystal, thereby reducing the diffraction of the liquid crystal display panel 1000 and improving the under-screen photographing effect thereof. Also, by designing the phase compensation layer 6 below the pixel electrode layer, the influence on the liquid crystal capacitance formed between the pixel electrode 39 and the common electrode can be reduced.
In other embodiments, the plurality of first sub-pixels 8 includes a plurality of first red sub-pixels, a plurality of first blue sub-pixels, and a plurality of first green sub-pixels, and the thickness of the plurality of phase compensation patterns 60 corresponding to each of the red sub-pixels, each of the first blue sub-pixels, and each of the first green sub-pixels is the same. In this way, the thickness of the liquid crystal display panel 1000 can be made substantially uniform.
In other embodiments, the phase compensation layer 6 may be disposed on the common electrode in order to reduce the influence on the liquid crystal capacitance formed between the pixel electrode 39 and the common electrode. The liquid crystal display panel 1000 may be a general liquid crystal display panel, and is not limited to the COA (Colorfilter On Array) type liquid crystal display panel.
In other embodiments, the phase compensation layer 6 may be the same material as the first passivation layer 36 and/or the second passivation layer 38, e.g., a dense silicon nitride material. Thus, not only the phase compensation function can be realized, but also the color resistance below can be further protected.
In other embodiments, the number of the first domains and the second domains is not limited to 2, and may be 1 or 4, for example. That is, the first subpixel 8 and the second subpixel 9 are not limited to a 4-domain structure, and may be, for example, a 2-domain or 8-domain structure.
In a possible embodiment, the phase compensation pattern 60 may be patterned to form a plurality of gaps, and the extending direction of the plurality of gaps is the same as the extending direction of the plurality of first slits 391a of the pixel electrode, the phase compensation pattern 60 overlaps the slits of the pixel electrode 39, and the gaps of the phase compensation pattern 60 overlap the pixel electrode.
The embodiment of the invention also provides a liquid crystal display device, which comprises the liquid crystal display panel 1000 and an optical sensor, wherein the optical sensor is positioned below the liquid crystal display panel 1000 and faces the light-transmitting display area DA1. The optical sensor is configured to receive light passing through the light-transmitting display area DA1, and illustratively, the optical sensor is a camera, and the processor of the liquid crystal display device may control the liquid crystal display panel 1000 to display a photo taken by the camera. The liquid crystal display device is a device having a display function, and may be a device displaying video or still images, including a fixed terminal such as a television, a desktop computer, a monitor, a billboard, a mobile terminal such as a mobile phone, a tablet computer, a mobile communication terminal, an electronic notepad, an electronic book, a multimedia player, a navigator, a notebook computer, and a wearable electronic device such as a smart watch, smart glasses, a virtual reality device, an augmented reality device, for example.
The foregoing has outlined rather broadly the more detailed description of embodiments of the invention, wherein the principles and embodiments of the invention are explained in detail using specific examples, the above examples being provided solely to facilitate the understanding of the method and core concepts of the invention; meanwhile, as those skilled in the art will have variations in the specific embodiments and application scope in light of the ideas of the present invention, the present description should not be construed as limiting the present invention.
