Abstract: A touch panel frame structure is provided and includes a first frame including positioning grooves, a second frame covered by the first frame, a third frame, and an adhesive layer. The second frame includes first fixing portions located in the positioning grooves. The third frame includes a body portion, a supporting portion located on an inner edge of the body portion, and positioning boards. Each of the positioning boards is connected to the body portion and is coupled to one of the positioning grooves. Each of the positioning boards includes a plurality of second fixing portions. Each of the second fixing portions is fastened to one of the first fixing portions, such that each of the positioning boards is detachably fixed in one of the positioning grooves. The adhesive layer is located on the supporting portion to adhere a touch panel assembly.

Abstract: A light bar fixing structure of a backlight module includes a reverse U-shaped frame, a light bar structure, and a fixing plate. The reverse U-shaped frame, which has an opening and multiple slits therein, is disposed on a back cover of the backlight module. The light bar structure includes a substrate and a plurality of light emitting devices. The fixing plate is attached to the substrate by using an adhesive layer. In addition, a plurality of buckling portions is provided in a periphery of the fixing plate, and by engaging the buckling portions with the slits, the fixing plate is fixed on the reverse U-shaped frame, which makes the light bar structure protrude from the opening of the reverse U-shaped frame after inserting through the opening. Therefore, regardless of light emitting device thickness, the light bar structure can be, in this manner, fixed on the back cover.
