Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display screens, and in particular to a peeping-proof liquid crystal display screen and an electronic device. Background Art

[0002] Liquid crystal displays (LCDs) are a common display device, primarily composed of liquid crystal molecules, polarizers, color filters, and backlights. Liquid crystal molecules rotate under the influence of an electric field, thereby changing the polarization direction of light and displaying images. However, LCDs have a wide viewing angle, making it easy for others to see the content on the screen in certain situations, leading to information leakage. Summary of the Invention

[0003] The main purpose of the present invention is to provide a peek-proof liquid crystal display screen and an electronic device, aiming to effectively solve the problems in the background technology.

[0004] In order to achieve the above-mentioned purpose, the technical solutions of the present utility model include:

[0005] The utility model discloses an anti-peep liquid crystal display screen, which comprises a liquid crystal box, wherein the liquid crystal box comprises a surface ITO layer, a bottom ITO layer, and liquid crystal molecules located between the surface ITO layer and the bottom ITO layer, wherein the surface ITO layer is composed of a plurality of surface ITO strip segments arranged longitudinally and evenly spaced; the bottom ITO layer is composed of a plurality of bottom ITO strip segments arranged longitudinally and evenly spaced; and a bottom ITO strip segment is correspondingly arranged below each surface ITO strip segment.

[0006] In a preferred embodiment, the width of the surface ITO strip segment is 28 microns to 32 microns, and the spacing between two adjacent surface ITO strip segments is 8 microns to 12 microns; the width of the bottom ITO strip segment is 31 microns to 35 microns, and the spacing between two adjacent bottom ITO strip segments is 10 microns.

[0007] In a preferred embodiment, the cross-section of the surface ITO strip segment is a polygonal structure or an arc structure.

[0008] In a preferred embodiment, the cross-section of the bottom ITO strip segment is a polygonal structure or an arc structure.

[0009] In a preferred embodiment, the anti-peeping LCD screen further includes a signal receiving device, which is electrically connected to the liquid crystal box and is used to receive an anti-peeping signal; when the signal receiving device receives the anti-peeping signal, the anti-peeping LCD screen is in a powered-on state and the anti-peeping function is turned on; when the signal receiving device does not receive the anti-peeping signal, the anti-peeping LCD screen is in a non-powered state and the anti-peeping function is turned off.

[0010] In a preferred embodiment, the anti-peeping signal is an electrical signal or an optical signal.

[0011] In a preferred embodiment, the anti-peeping liquid crystal display screen further includes a surface substrate glass connected to the surface ITO layer; and a bottom substrate glass connected to the bottom ITO layer.

[0012] The utility model also discloses an electronic device, which comprises the anti-peeping liquid crystal display screen as described above.

[0013] The beneficial effects of the utility model are:

[0014] The utility model discloses a privacy-preventing liquid crystal display screen, which is applied to electronic devices. The screen comprises a surface ITO layer formed by a plurality of longitudinally and evenly spaced surface ITO strip segments, and a bottom ITO layer formed by a plurality of longitudinally and evenly spaced bottom ITO strip segments. Each surface ITO strip segment is correspondingly disposed below a bottom ITO strip segment. By varying the voltage applied to the liquid crystal molecules, the degree of distortion of the liquid crystal molecules is controlled, thereby controlling the transmission of light. The privacy-preventing liquid crystal display screen is in a light-transmitting state when privacy protection is not required. When privacy protection is required, the application of voltage causes the liquid crystal molecules to distort, narrowing the visible range so that users can only view images within a certain viewing range. Those within the privacy protection range see a black louver grille on the screen, preventing them from viewing the full image. This effectively prevents privacy and protects user privacy.

[0024] In order to better illustrate the present invention, the present invention is further described in detail below with reference to the accompanying drawings.

[0025] It should be clear that the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the embodiments of the present application.

[0026] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the embodiments of the present application. The singular forms "a," "the," and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0027] Combine Figures 1 to 5 As shown, Figure 1 1 is a schematic diagram of the side structure of the liquid crystal cell; Figure 2 It is the distribution diagram of the surface ITO strip segment and the bottom ITO strip segment; Figure 3 It is a schematic diagram of the structure of the surface substrate glass and the surface ITO layer; Figure 4 It is a schematic diagram of the structure of the bottom substrate glass and the bottom ITO layer; Figure 5 It is a schematic diagram of the display of the LCD screen when the user is within the privacy protection range; Figure 5 The white strip segments in the middle represent the louver grille structure, and the black portion represents the screen. The utility model discloses a privacy-protected liquid crystal display screen 5, comprising a liquid crystal cell comprising a top ITO layer 1, a bottom ITO layer 2, and liquid crystal molecules (not shown) located between the top ITO layer 1 and the bottom ITO layer 2. The top ITO layer 1 is composed of a plurality of top ITO strip segments 11 arranged longitudinally and evenly spaced apart; the bottom ITO layer 2 is composed of a plurality of bottom ITO strip segments 21 arranged longitudinally and evenly spaced apart; and each top ITO strip segment 11 is correspondingly disposed below one bottom ITO strip segment 21.

[0028] Furthermore, the width P1 of the surface ITO strip segment 11 is 28 microns to 32 microns, and the spacing W1 between two adjacent surface ITO strip segments is 8 microns to 12 microns; the width P2 of the bottom ITO strip segment is 31 microns to 35 microns, and the spacing W2 between two adjacent bottom ITO strip segments is 10 microns. According to the above size specifications, an ultra-fine louver grille effect can be formed, effectively improving the anti-peeping effect.

[0029] Preferably, the width P1 of the surface ITO strip segment can be 28 microns, 30 microns, or 32 microns, and the spacing W1 between two adjacent surface ITO strip segments is 8 microns, 10 microns, or 12 microns; the width W2 of the bottom ITO strip segment is 31 microns, 33 microns, or 35 microns.

[0030] Furthermore, the cross-sectional shape of the surface ITO strip segment is a polygonal structure or an arc structure, such as a triangle, a quadrilateral, a semicircle, etc.

[0031] Furthermore, the cross-section of the bottom ITO strip segment is a polygonal structure or an arc structure, such as a triangle, a quadrilateral, a semicircle, etc.

[0032] Specifically, by precisely controlling the cross-sectional shape and spacing of the top and bottom ITO strips, the liquid crystal molecules can rotate more precisely under the action of the electric field, thereby improving the privacy protection effect. This design not only improves the privacy protection effect of the privacy-protected LCD screen, but also reduces the difficulty and cost of manufacturing.

[0033] Furthermore, the anti-peeping LCD screen 5 also includes a signal receiving device electrically connected to the liquid crystal box for receiving an anti-peeping signal. When the signal receiving device receives the anti-peeping signal, the anti-peeping LCD screen is powered on, and the anti-peeping function is enabled. When the signal receiving device does not receive the anti-peeping signal, the anti-peeping LCD screen is powered off, and the anti-peeping function is disabled. Finally, during use, the anti-peeping LCD screen 5 only needs to apply voltage when anti-peeping is required, without the need for continuous voltage application. This can effectively save energy and extend the life of the screen.

[0034] Furthermore, the anti-peeping signal is an electrical signal or an optical signal. It should be noted that the generation and reception means of the anti-peeping signal of the present invention are both conventional technical means.

[0035] Furthermore, the anti-peeping liquid crystal display screen 5 further includes a surface substrate glass 3, which is connected to the surface ITO layer; and a bottom substrate glass 4, which is connected to the bottom ITO layer.

[0036] The utility model further discloses an electronic device, which includes the anti-peeping liquid crystal display screen 5 as described above.

[0037] The beneficial effects of the utility model are:

[0038] The utility model discloses a privacy-preventing liquid crystal display screen 5, which is applied to electronic devices and comprises a surface ITO layer composed of a plurality of longitudinally and evenly spaced surface ITO strip segments and a bottom ITO layer composed of a plurality of longitudinally and evenly spaced bottom ITO strip segments. Each surface ITO strip segment is correspondingly disposed below a bottom ITO strip segment. By varying the voltage applied to the liquid crystal molecules, the degree of distortion of the liquid crystal molecules is controlled, thereby controlling the transmission of light. The privacy-preventing liquid crystal display screen is in a light-transmitting state when privacy protection is not required. When privacy protection is required, a voltage is applied to cause the liquid crystal molecules to distort, narrowing the visible range so that the user can only view the image within a certain viewing range. Those within the privacy protection range see a black louver grille on the privacy-preventing liquid crystal display screen 5, preventing them from viewing the entire image. This prevents privacy and effectively protects user privacy.

[0039] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
