[0031] DETAILED DESCRIPTION
[0032] For the purposes of the present application, a more complete description of which will follow, reference will be made to the accompanying drawings referenced below. The drawings illustrate embodiments of the application. However, the application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and fully convey the scope of the application to those skilled in the art.
[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for describing particular embodiments only and is not intended to be limiting of the application.
[0034] Spatially relative terms, such as "beneath", "below", "lower", "under", "above", "upper" and the like, can be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use and / or operation in addition to the orientations depicted in the figures. For example, if a device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" or "over" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. The devices can be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
[0035] As used herein, the singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise. It will be further understood that the terms "comprises", "comprising", "includes" and / or "including", or the like, as used herein, specify the presence of stated features, integers, steps, operations, elements, components, or combinations thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or combinations thereof.
[0036] In the process of liquid crystal control, the deflection of liquid crystal needs to be controlled to realize image display. Since the deflection of liquid crystal is controlled by voltage, when there is a voltage difference, the liquid crystal will change from a light-transmitting state to a light-blocking state or from a light-blocking state to a light-transmitting state with the change of the pressure difference. However, in the existing liquid crystal on silicon chip, when driving the liquid crystal, due to the gap between the pixel electrodes, light will pass through the gap into the underlying circuit, affecting the deflection state of the liquid crystal. For example, the liquid crystal cannot be kept flat although it is deflected, so that it cannot present a light-blocking state, thereby making the dark field of the display picture not dark enough, resulting in poor display effect.
[0037] In view of the above problems, the embodiment of the present application provides a silicon-based liquid crystal chip and a display device. The light shielding structure is arranged on the driving substrate. In this way, the light shielding structure can shield external light, which helps to reduce the light from the gap between the pixel electrodes and enter into the driving substrate, thereby reducing the influence on the deflection of the liquid crystal in the liquid crystal assembly, and helps to ensure the normal work of the liquid crystal assembly, thereby improving the display effect of the silicon-based liquid crystal chip.
[0038] In a first aspect, referring to Figure 1 and Figure 2 The embodiment of the present application provides a silicon-based liquid crystal chip 10, which comprises a driving substrate 11, a light shielding structure 12 and a plurality of pixel electrodes 13. The light shielding structure 12 is arranged on one side of the driving substrate 11. The plurality of pixel electrodes 13 are arranged at intervals on the side of the light shielding structure 12 away from the driving substrate 11. A liquid crystal assembly 14 is arranged on the side of the light shielding structure 12 away from the driving substrate 11.
[0039] It can be understood that the pixel electrode 13 is electrically connected with the driving substrate 11.
[0040] The driving substrate 11 can include a semiconductor substrate (not shown in the figure) and a driving structure layer (not shown in the figure) arranged on the semiconductor substrate, and the driving circuit and the peripheral circuit are arranged in the driving structure layer. The driving substrate 11 is provided with a central area 11a and a peripheral area 11b, and the peripheral area 11b is arranged around the outer periphery of the central area 11a. The driving circuit is arranged in the central area 11a and is electrically connected with the pixel electrode 13. The peripheral circuit is arranged in the peripheral area 11b and is electrically connected with the driving circuit. Further, the peripheral area 11b is also provided with a contact pad 111, which is used for electrical connection with the circuit board.
[0041] In one example, the liquid crystal assembly 14 comprises a liquid crystal 141, a frame 142 and a transparent substrate 143, wherein the frame 142, the transparent substrate 143 and the driving substrate 11 together form a containing cavity for containing the liquid crystal 141. Exemplarily, the frame 142 can be a frame glue, and the transparent substrate 143 can be a transparent conductive glass (such as ITO glass).
[0042] The silicon-based liquid crystal chip 10 provided by the embodiment of the present application is arranged with the light shielding structure 12 on the driving substrate 11. In this way, the light shielding structure 12 can shield external light, which helps to reduce the light from the gap between the pixel electrodes 13 and enter into the driving substrate 11, thereby reducing the influence on the deflection of the liquid crystal 141 in the liquid crystal assembly 14. Therefore, it is ensured that the liquid crystal 141 can lie flat after deflection, which helps to maintain the liquid crystal 141 in a non-transparent state, thereby helping to improve the blackness of the silicon-based liquid crystal chip 10 in the dark field, and further helping to improve the display effect of the silicon-based liquid crystal chip 10.
[0043] It should be noted that the light shielding structure 12 can also be a reflective structure, that is, the light shielding structure 12 has both light shielding and light reflecting functions.
[0044] In one embodiment, the light shielding structure 12 includes a first light shielding layer 121, and a projection of the first light shielding layer 121 on the driving substrate 11 covers at least part of a gap between projections of two adjacent pixel electrodes 13 on the driving substrate 11. It can be understood that, in one example, the projection of the first light shielding layer 121 covers only part of the gap between the projections of the two adjacent pixel electrodes 13. In another example, the projection of the first light shielding layer 121 covers the gap between the projections of any two adjacent pixel electrodes 13.
[0045] In this way, the first light shielding layer 121 can shield at least part of the light, thereby reducing the light from the gap between the pixel electrodes 13 and entering the driving substrate 11, which is conducive to making the liquid crystal 141 lie flat after deflection and maintaining the non-transparent state, thereby improving the blackness of the liquid crystal on silicon chip 10 in the dark field, and further improving the display effect of the liquid crystal on silicon chip 10.
[0046] In one embodiment, referring to FIG. 1, the first light shielding layer 121 includes a plurality of first light shielding portions 1211 arranged at intervals along the first direction X, and each first light shielding portion 1211 extends along a second direction Y intersecting the first direction X; the first direction X and the second direction Y are both perpendicular to the thickness direction of the driving substrate 11. Figure 3
[0047] Further, the liquid crystal on silicon chip 10 includes a plurality of columns of pixel electrodes 13 arranged at intervals along the first direction X, and two adjacent columns of pixel electrodes 13 are spaced apart from each other; each column of pixel electrodes 13 is arranged between two adjacent first light shielding portions 1211; and a projection of each column of pixel electrodes 13 on the driving substrate 11 overlaps with projections of the two adjacent first light shielding portions 1211 on the driving substrate 11.
[0048] In this way, the amount of material of the first light shielding layer 121 can be reduced, which is conducive to reducing the cost and lowering the process difficulty.
[0049] In one embodiment, the first light shielding layer 121 includes a conductive material, and the liquid crystal on silicon chip 10 includes at least one voltage potential and at least one signal line. A single voltage potential or a single signal line is connected to at least one first light shielding portion. In this way, the first light shielding layer 121 not only has the function of light shielding, but also can provide electrical signals as a trace.
[0050] In one embodiment, the silicon-based liquid crystal chip 10 includes a first voltage potential. A first light-shielding layer 121 is electrically connected to the first voltage potential. Thus, the first light-shielding layer 121 not only has the function of blocking light, but can also provide a voltage signal.
[0051] In one specific embodiment, the power supply traces can be patterned. Specifically, based on the original power supply traces, the area of the power supply traces is increased so that the orthographic projection of the power supply traces on the driving substrate 11 covers at least part of the gap between the orthographic projections of two adjacent pixel electrodes 13 on the driving substrate 11.
[0052] It should be noted that when the first light-shielding layer 121 is connected to the first voltage potential, the first light-shielding layer 121 provides the first power supply signal to the silicon-based liquid crystal chip.
[0053] In one embodiment, the first light-shielding layer 121 is a full-surface structure, and the orthographic projection of the first light-shielding layer 121 on the driving substrate 11 covers the gap between the orthographic projections of any two adjacent pixel electrodes 13 on the driving substrate 11. In this way, the light-shielding effect of the first light-shielding layer 121 can be better.
[0054] In one embodiment, reference Figure 2 and Figure 3 As shown, the light-shielding structure 12 also includes a second light-shielding layer 122, which is disposed on one side of the first light-shielding layer 121; the orthographic projection of the second light-shielding layer 122 on the driving substrate 11 covers at least part of the gap between the orthographic projections of two adjacent pixel electrodes 13 on the driving substrate 11.
[0055] Understandably, in one example, only a subset of the orthographic projections of two adjacent pixel electrodes 13 have the orthographic projection of the second light-shielding layer 122 between their orthographic projections. In another example, in all adjacent pixel electrodes 13, the orthographic projection of any two adjacent pixel electrodes 13 has the orthographic projection of the second light-shielding layer 122 between their orthographic projections.
[0056] Thus, the second light-shielding layer 122 can block at least part of the light, thereby reducing the light from passing through the gap between the pixel electrodes 13 and entering the driving substrate 11. This is beneficial for the liquid crystal 141 to lie flat after deflection and maintain an opaque state, thereby improving the blackness of the silicon-based liquid crystal chip 10 in dark fields, and thus improving the display effect of the silicon-based liquid crystal chip 10.
[0057] In one of the embodiments, the second light shielding layer 122 includes a plurality of second light shielding portions 1221 arranged along the second direction Y, each of the second light shielding portions 1221 extending along the first direction X. The orthographic projection of the first light shielding portion 1211 on the driving substrate 11 and the orthographic projection of the second light shielding portion 1221 on the driving substrate 11 overlap each other.
[0058] In this way, on the one hand, the amount of material of the second light shielding layer 122 can be reduced, which is conducive to reducing the cost; and on the other hand, the combination of the first light shielding portion 1211 and the second light shielding portion 1221 is conducive to improving the light shielding capability of the light shielding structure 12.
[0059] Further, the silicon-based liquid crystal chip 10 includes a plurality of rows of pixel electrodes 13 arranged along the second direction Y, and adjacent two rows of pixel electrodes 13 are spaced apart from each other; each row of pixel electrodes 13 is arranged between adjacent two second light shielding portions 1221; and the orthographic projection of each row of pixel electrodes 13 on the driving substrate 11 and the orthographic projection of the adjacent two second light shielding portions 1221 on the driving substrate 11 overlap each other.
[0060] In one of the embodiments, the second light shielding layer 122 includes a conductive material, and the silicon-based liquid crystal chip 10 includes at least one voltage potential and at least one signal line. The single voltage potential or the single signal line is electrically connected to at least one second light shielding portion 1221. In this way, the second light shielding layer 122 not only has the function of light shielding, but also can provide electrical signals as a wiring.
[0061] In one of the embodiments, the silicon-based liquid crystal chip 10 includes a second voltage potential. The second light shielding layer 122 is electrically connected to the second voltage potential. In this way, the second light shielding layer 122 not only has the function of light shielding, but also can provide a voltage signal.
[0062] In a specific embodiment, the power supply wiring can be subjected to a graphic processing. Specifically, on the basis of the original power supply wiring, the area of the power supply wiring is increased, so that the orthographic projection of the power supply wiring on the driving substrate 11 covers at least part of the gap between the orthographic projections of the adjacent two pixel electrodes 13 on the driving substrate 11.
[0063] It should be noted that, in the case that the second light shielding layer 122 is connected to the second voltage potential, the first light shielding layer 122 provides a second power supply signal for the silicon-based liquid crystal chip 10.
[0064] In one of the embodiments, the first voltage potential and the second voltage potential are different. In this way, the light shielding structure 12 can provide a plurality of different voltage signals for the silicon-based liquid crystal chip 10.
[0065] In one of the embodiments, the first voltage potential is higher than the second voltage potential. The size of the first light shielding portion 1211 along the first direction X is greater than the size of the second light shielding portion 1221 along the second direction Y. Here, the size of the first light shielding portion 1211 along the first direction X is the width of the first light shielding portion 1211, and the size of the second light shielding portion 1221 along the second direction Y is the width of the second light shielding portion 1221. Exemplarily, the first voltage potential can be 5V, and the second voltage potential can be 3V.
[0066] It can be understood that the higher the voltage is, the thicker the corresponding wire is. By making the width of the first light shielding portion 1211 greater than the width of the second light shielding portion 1221, it is beneficial to make the first light shielding layer 121 thin, thereby realizing the thinness of the liquid crystal chip 10, and according to the voltage, the width and thickness of the wires of the first light shielding portion 1211 and the second light shielding portion 1221 are designed, which can better allocate the power consumption of the chip, realize the thinness of the liquid crystal chip 10 while meeting the power consumption demand.
[0067] It should be noted that the first voltage potential can also be lower than the second voltage potential. Then, the size of the first light shielding portion 1211 along the first direction X is smaller than the size of the second light shielding portion 1221 along the second direction Y.
[0068] It can be understood that the size of the first light shielding portion 1211 along the first direction X can also be equal to the size of the second light shielding portion 1221 along the second direction Y.
[0069] In one of the embodiments, the plurality of first light shielding portions 1211 are arranged at equal intervals along the first direction X, and the plurality of second light shielding portions 1221 are arranged at equal intervals along the second direction Y. In this way, the first light shielding portion 1211 and the second light shielding portion 1221 can be arranged more regularly, which matches the arrangement rule of the pixel electrode 13.
[0070] In one of the embodiments, the light shielding structure 12 further comprises a first insulating layer 123, the first insulating layer 123 is provided with a plurality of pixel openings 12a away from one side of the driving substrate 11, and the plurality of pixel electrodes 13 are correspondingly arranged in the plurality of pixel openings 12a; the first light shielding layer 121 is arranged in the first insulating layer 123, and the second light shielding layer 122 is arranged on the side of the first insulating layer 123 close to the driving substrate 11.
[0071] By arranging the first insulating layer 123, the first light shielding layer 121 and the second light shielding layer 122 can be insulated, so as to prevent the first light shielding layer 121 and the second light shielding layer 122 from being electrically interfered.
[0072] In one example, the plurality of pixel electrodes 1313 are arranged one by one in the plurality of pixel openings 12a.
[0073] In one embodiment, the silicon-based liquid crystal chip 10 further includes a wiring layer 15 disposed between the driving substrate 11 and the light-shielding structure 12. Specifically, the wiring layer 15 can connect the driving substrate 11 and the pixel electrode 13 (or the light-shielding structure 12).
[0074] In one embodiment, the silicon-based liquid crystal chip 10 further includes a second insulating layer 16, which is disposed between the wiring layer 15 and the light-shielding structure 12.
[0075] Secondly, embodiments of this application provide a display device, which may be a projector, projection system, or other projection device with a silicon-based liquid crystal chip. (Refer to...) Figure 5 The diagram shown is a functional module schematic of display device 1.
[0076] Specifically, the display device 1 includes the silicon-based liquid crystal chip 10 as described in the second aspect. It is understood that the display device 1 also includes a light source 20, a projection lens 30, a housing 40, etc. The light source 20 and the silicon-based liquid crystal chip 10 are disposed within the housing 40, and the projection lens 30 is disposed on the housing 40. The light emitted by the light source 20 illuminates the silicon-based liquid crystal chip 10, and the projection lens 30 projects the optical image generated by the silicon-based liquid crystal chip 10 onto a screen or wall.
[0077] The display device 1 provided in this application embodiment has a light-shielding structure 12 provided on the driving substrate 11. In this way, the light-shielding structure 12 can block external light, helping to reduce the amount of light passing through the gaps between the pixel electrodes 13 and entering the driving substrate 11. This reduces the impact on the deflection of the liquid crystal 141 in the liquid crystal assembly 14, thus ensuring that the liquid crystal 141 can lie flat after deflection. This helps maintain the liquid crystal 141 in an opaque state, thereby improving the blackness of the silicon-based liquid crystal chip 10 in dark conditions and ultimately improving the display effect of the silicon-based liquid crystal chip 10.

For the sake of brevity, not all possible combinations of the technical features of the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0080] The above embodiments only express several implementation ways of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation to the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application.
