Abstract:
1. An image display module for displaying images in electronic devices, comprising: a bottom cover; a screen received in the bottom cover; an upper cover fastened and aligned to the bottom cover, the upper cover having an opening defined therein for exposing the screen and displaying images; a sensor on the upper cover, wherein the sensor is capable of engaging a circuit means at a position to control the size of the display area of the screen; and a sliding portion movably mounted on the bottom cover, wherein the sliding portion can stop at different positions relative to the bottom cover to expose different-sized portions of the screen, and wherein the sliding portion is capable of engaging the sensor together with the circuit means to control the size of the display area of the screen based on the position of the sliding portion; wherein the sensor is arranged on the upper cover, and a first position and a second position are defined for the sliding portion; wherein, when the sliding portion is at the first position, the sliding portion does not engage the sensor, the opening is partially covered by the sliding portion and a portion of the screen is exposed for displaying images, and when the sliding portion moves to the second position relative to the bottom cover, the opening is in its full size and the sliding portion engages the sensor which, in turn, engages the circuit means to use the full size of the screen to display images; wherein the bottom cover comprises a frame for receiving the screen therein and two arms extending inwardly from two opposite sides of the frame respectively, two grooves being defined in each of the arms for engaging with the sliding portion; wherein each of the arms comprises a hanging portion extending inwardly from one of the two opposite sides of the frame and a conducting portion extending upwardly from one end of the hanging portion, the two grooves being defined in an outer side of the conducting portion; wherein the sliding portion comprises a sliding element, the sliding element comprising a body and two locking blocks extending rearward from two ends of the body, each of the two locking blocks being movably mounted on the connecting portion of each of the arms; wherein each of the two locking blocks comprises a leg extending from one of the two ends of the body and a bulge formed inwardly at an end of the leg, the bulge being received in one of the two corresponding grooves of each of the arms of the bottom cover to securely lock the sliding portion at the first position or the second position; and wherein a positioning plate extends upwardly from a rear side of the body and positions between the two locking blocks, the positioning plate being capable of engaging or disengaging with the sensor when the bulge of each of the two blocks is alternatively received in one of the two corresponding grooves of each of the arms of the bottom cover.
