An anti-peep module including an anti-peep element, a driving circuit, a voltage adjustment circuit and a temperature sensor is provided. The anti-peep element includes a liquid crystal layer, a first anti-peep electrode layer and a second anti-peep electrode layer. The liquid crystal layer is located between the first and second anti-peep electrode layers. The temperature sensor is adapted to sense an ambient temperature. The voltage adjustment circuit is coupled to the temperature sensor. The driving circuit is coupled to the voltage adjustment circuit and the anti-peep element. When the ambient temperature is a first ambient temperature and the anti-peep element operates in an anti-peep mode, the driving circuit outputs a first driving voltage to the anti-peep element; when the ambient temperature is a second ambient temperature and the anti-peep element operates in the anti-peep mode, the driving circuit outputs a second driving voltage to the anti-peep element.

A reflective display panel includes a first substrate and a second substrate. A thin film transistor and a reflective layer are disposed on the first substrate. A color resist layer is disposed on the second substrate. The reflective display panel includes a color sub-pixel region and a white sub-pixel region adjacent to each other. The color sub-pixel region has the color resist layer, and the white sub-pixel region has no color resist layer. A buffer layer is disposed in the white sub-pixel region on the first substrate or the second substrate. A cell gap between the first substrate and the second substrate in the white sub-pixel region is smaller than a cell gap between the first substrate and the second substrate in the color sub-pixel region. In this way, reflectivity and chromaticity can be improved.

The disclosure provides a touch display panel including a substrate and a first mesh electrode. The first mesh electrode is disposed on the substrate and includes a plurality of first extending portions, a plurality of second extending portions, and a plurality of first disconnection regions. The first extending portions are arranged along a first direction and extend in a second direction. The first direction intersects with the second direction. The second extending portions are arranged along the second direction and extend in the first direction. The first disconnection regions are arranged along the first direction and extend in the second direction. The first disconnection regions overlap the second extending portions and do not overlap the first extending portions.

A reflective LCD panel includes a color filter substrate, an array substrate, a liquid crystal layer and a polarizing film. The array substrate and the color filter substrate are disposed oppositely. The liquid crystal layer is disposed between the color filter substrate and the array substrate and has an alignment direction. The polarizing film is disposed on the color filter substrate, and color coordinates of the polarizing film in the CIE1976 color space are (a, b), wherein 0.05&#x2264;a&#x2264;0.2 and &#x2212;5&#x2264;b&#x2264;0. The liquid crystal layer has a birefringence difference &#x394;n, the liquid crystal layer has a thickness (d), when the reflective LCD panel is in a white frame, 2&#x394;n*d=&#x394;&#x3bb; is satisfied, &#x394;&#x3bb; is the optical path difference obtained when a forward light vertically enters the liquid crystal layer and is reflected by the array substrate, and 120 nm&#x2264;&#x394;n*d&#x2264;170 nm.
