In the related art, in order to solve the problem that peeping-proof membrane exists, electronic manufacturers has proposed a peeping-proof membrane, including upper electrode layer, the lower electrode layer that sets up from top to bottom, set up a plurality of first regulation layers and the second regulation layer that set up in proper order interval between upper electrode layer and the lower electrode layer, the width of first regulation layer is greater than the width of second regulation layer, and when the circular telegram, the transmissivity of first regulation layer is less than first threshold value, and the second threshold value of second regulation layer is greater than the second threshold value, and the second threshold value is greater than or equal to first threshold value, has realized peeping-proof effect. However, the peep-proof effect is not ideal, and the first adjusting layer and the second adjusting layer with different thresholds are set, so that the screen has different transmittance, and the look and feel of the user are affected. Meanwhile, the areas of the upper electrode layer and the lower electrode layer are too large, the display area of a screen is affected, the areas are too small, the electric connection is unstable, the failure is easy, and the peep-proof effect cannot be achieved. When the peep-proof film is arranged on the screen, collapse is easy to occur, and the flatness of the screen is affected.

The utility model provides a peep-proof screen, including peep-proof layer, peep-proof layer includes the supporting part that a plurality of intervals set up and the conductive color changing part that a plurality of intervals set up, and the supporting part is in proper order alternately arranged along first default direction with conductive color changing part. Wherein, the conductive color-changing part comprises a color-changing film layer which is made of electrochromic materials and changes color when the conductive color-changing part is electrified. The support parts and the conductive color-changing parts are alternately arranged in the present disclosure to provide a support effect for the conductive color-changing parts, avoid collapse of the conductive color-changing parts, and ensure that the conductive color-changing parts can be used normally. The conductivity color-changing part is used for electrifying and changing, so that the transmittance of the screen is reduced, the privacy of a user is protected, and the peeping prevention function is realized.

In an exemplary embodiment, as shown in fig. 1 and 2, the peep-proof screen includes a peep-proof layer 1, where the peep-proof layer 1 includes a plurality of support portions 11 disposed at intervals and a plurality of conductive color-changing portions 12 disposed at intervals, and the support portions 11 and the conductive color-changing portions 12 are sequentially and alternately arranged along a first preset direction (refer to an X axis shown in fig. 1). The support portion 11 is connected to the conductive color-changing portion 12, and the height of the support portion 11 (refer to the Y axis shown in fig. 1) along the second preset direction is the same as the height of the conductive color-changing portion, and the second preset direction is perpendicular to the first preset direction.

When other structures of the peep-proof screen are covered on the peep-proof layer 1, the supporting portion 11 can provide a supporting effect for the conductive color-changing portion 12, so that the conductive color-changing portion 12 is prevented from being collapsed, and the flatness of the conductive color-changing portion 12 is ensured. The supporting portion 11 is made of transparent glass material, for example, so that the supporting portion 11 has good light transmittance and supporting strength.
