In a backlight module, a liquid crystal display screen, and a using method thereof provided, the liquid crystal display screen includes a liquid crystal display panel, a backlight module switchable between a transparent state and a backlight state, and an optical component. Without disrupting full screen display and increasing a possibility of cellphone damages, the backlight module may solve a problem that the liquid crystal display screen is opaque to light, such that the screen is normally displayed, and the optical component is operated on the same liquid crystal display screen.

Backlight module, liquid crystal display screen, and using method thereof

Disclosed is a micro-lens imaging multi-well test plate which comprises: a transparent plate of 3-5 mm in thickness with one or more trapezoidal wells locating in the middle of the plate, each of the wells is of an underside of 2-4 mm in diameter, 0.2-0.5 mm in thickness, a trapezoidal dip angle of 60-75&#xb0;, and has a micro-lens which upper half is hemispherical, lower half is a cylinder, with radius of 0.1&#x2dc;1.0 mm, height of 0.2&#x2dc;2.5 mm, molded on the bottom of the well. The micro-lens imaging multi-well test plate is made of homogeneous optical transparent materials. When the trapezoidal concave wells of the test plate are filled with fluid to immerse the micro-lens, under parallel light illumination, due to the refraction effect of light, the image of micro-lens is a round one with an outer edge that is a black ring. The outer radius R of the black ring is the radius of the micro-lens, the inner radius r of the black ring is a function of the refractive index nof the immersion liquid, the refractive index nof the micro-lens and the height h of the micro-lens, so the refractive index of the sample fluid can be determined by monitoring the value of the inner radius r of the black ring with known values of R, nand h. By using a multi-well test plate for imaging, the individual refractive indices of different sample fluids in all the wells can be determined simultaneously in one measurement.

Micro-lens imaging multi-well test plate

A replaceable panel device () includes a panel () with a mounting portion (), a locking subassembly (), and a top cover () with a block (). The mounting portion has at least one slideway (), a recess (), and two locating grooves (). The locking subassembly is accommodated in the mounting portion of the panel. The locking subassembly has a button (), an elastic rod (), and a slider (). The button has at least one rail (), a hole () defined at top of the rail. The slider has at least one slot () and a rabbet (). The slider is received in the recess. The rail is received through the slideway and the slot. The elastic rod is received through the hole. Ends of the elastic rod are located in the locating grooves. The rabbet engagingly receives the block of the top cover.

Replaceable panel device for a handset

A connecting mechanism for a battery case and a main body of a portable electronic device includes a main body (), a connecting member (), a cover (), and a shaft (). The main body has a receptacle (), and a recessed portion () for receiving the battery case. The connecting member has a body () and one or more mounting portions (). The cover defines a sliding space. The shaft extends through the mounting portions and is received in the receptacle. Thus the connecting member is rotatable relative to the main body about the shaft. The connecting member is received in the sliding space and can slide along the sliding space relative to the cover. Thus the cover is both rotatable and slidable relative to the main body, and need not be detached from the main body.

Connecting mechanism for a battery case and a body of a portable electronic device

An enclosure of a mobile phone with changeable panel includes a front cover (), a panel (), a rotatable holder (), and a spring (). The front cover defines a through hole () and latch slots (). The panel has projections () at an edge thereof, and the projections can be engaged in the latch slots of the front cover. The panel further has a hole () corresponding to the through hole of the front cover. The holder has a latch portion (), and the spring is engaged around the holder. The holder with the spring is received in the hole of the panel, and the holder is further received in the through hole of the front cover. The holder is rotated and the spring is compressed, thereby securely holding the panel on the front cover.
