As used herein, an "electronic device" (or simply "terminal") includes, but is not limited to, an apparatus that is configured to receive/transmit communication signals via a wireline connection, such as via a Public Switched Telephone Network (PSTN), a Digital Subscriber Line (DSL), a digital cable, a direct cable connection, and/or another data connection/network, and/or via a wireless interface (e.g., for a cellular network, a Wireless Local Area Network (WLAN), a digital television network such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter, and/or another communication terminal). A communication terminal arranged to communicate over a wireless interface may be referred to as a "wireless communication terminal", "wireless terminal" or "mobile terminal". Examples of mobile terminals include, but are not limited to, satellite or cellular telephones; a Personal Communications System (PCS) terminal that may combine a cellular radiotelephone with data processing, facsimile and data communications capabilities; PDAs that may include radiotelephones, pagers, internet/intranet access, Web browsers, notepads, calendars, and/or Global Positioning System (GPS) receivers; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver. A cellular phone is an electronic device equipped with a cellular communication module.

Referring to fig. 1 and fig. 2 together, fig. 1 is a schematic overall structure diagram of an embodiment of an electronic device of the present application, and fig. 2 is a schematic structure diagram of another view angle of the electronic device in the embodiment of fig. 1; the electronic component in this embodiment includes a protective case 100 and an electronic device 200; fig. 1 and 2 are schematic views illustrating a state in which the protective case 100 and the electronic apparatus 200 are assembled together. Referring to fig. 3, fig. 3 is a schematic structural diagram illustrating a disassembled state of the electronic device in the embodiment of fig. 1. It should be noted that the electronic device 200 in the present application may include a mobile phone, a tablet computer, a notebook computer, a wearable device, and the like. The protective case 100 for an electronic device in the embodiment of the present application includes a main case 110, where the main case 110 includes a first surface 111, a second surface 112, and a side surface 113 connecting the first surface 111 and the second surface 112, and an electronic drawing board 120 is embedded in the first surface 111. It should be noted that the terms "comprises" and "comprising," and any variations thereof, in the embodiments of the present application, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or may alternatively include other steps or elements inherent to such process, method, article, or apparatus.

Alternatively, the electronic drawing pad 120 may be a liquid crystal writing pad or a tablet, etc. The embodiments of the present application are not particularly limited. The main structure of the liquid crystal handwriting board includes a liquid crystal screen (film) 121 and a PCBA (short for Printed circuit board Assembly), that is, a PCB blank board is formed into a control circuit board after being subjected to SMT loading or being subjected to DIP-in-package (short for PCBA). The liquid crystal screen 121 is composed of a fog film, an ITO film, a liquid crystal film, an ITO film and a black film from top to bottom, and the thickness, color, brightness, contrast, writing resistance and aging resistance of the product are determined by the selection of film materials and the formula of the liquid crystal. The liquid crystal in the liquid crystal panel 121 is generally a bistable cholesteric liquid crystal, which is flat and arranged in layers with the molecules in the layers parallel to each other. FC state: the molecular long axis is perpendicular to the layer plane, with slight variations in the molecular long axis direction for different layers. P state: the long molecular axes are parallel to the layer plane, and the long molecular axes of different layers are slightly changed and arranged into a spiral structure along the normal direction of the layers. The thread distance of the cholesteric liquid crystal can be adjusted by the chiral polymer, when reaching 450nm-530nm, the handwriting is blue-green, when reaching 530-600 nm, the handwriting is yellow-green, and the required color is adjusted by different proportions of the chiral polymer. In the FC state, light rays directly penetrate through the liquid crystal layer and are absorbed by the black film at the lowest layer, and the complete black state is presented; when the liquid crystal screen 121 is pressed by fingers, liquid crystal is extruded and overturned by pressure, the overturned area is in a P state, when natural light irradiates the overturned area of the liquid crystal layer, only light with the wavelength same as the distance of the liquid crystal threads is reflected, and other colors are absorbed to form handwriting with corresponding colors.

Further, the first surface 111 of the main housing 110 is further provided with a key 122, and the key 122 is connected with the PCBA for controlling the working state of the liquid crystal screen 121. The keys 122 may include a clear key, a save key, and a power key (the power key controls power on and off of the electronic drawing board, the clear key is used for erasing an image drawn by the liquid crystal screen 121, and the save key is used for implementing a function of saving a text). When the clear key on the electronic drawing board 120 is pressed, the PCBA (not shown) powers on the liquid crystal panel 121, and the reversed area returns to the FC state by the voltage stimulus. The FC state and the P state are so-called bistable states, and mutual conversion between the FC state and the P state can be realized by a driving voltage.
