Display device with connector board on back of lower frame connecting to circuit board at back of lower substrate
View Patent ↗In a display device forming a board for mounting a connector which allows inputting of video data thereon and a board for mounting a display control circuit to be connected to the connector thereon on a surface of a display module opposite to an observation side, the board for mounting the connector thereon and the board for mounting the display control circuit thereon are physically separated from each other and, further, an area of the board for mounting the display control circuit thereon is set smaller than an area of the board for mounting the connector thereon.
1. A liquid crystal display device comprising:
a liquid crystal display panel having a pair of transparent substrate and liquid crystal composition sandwiched between the pair of transparent substrates, the pair of transparent substrates including a lower substrate having a pixel electrode;
an upper frame which is formed with an opening in a display region of the liquid crystal display panel;
a lower frame;
a backlight arranged between the liquid crystal display panel and the lower frame;
a circuit board located back of the lower substrate, the circuit board mounting a display control circuit thereon, the display control circuit driving the liquid crystal display device; and
a connector board having connector which is connected to the circuit board, the connector board extending in a direction of a long side of the lower frame which has a rectangular shaped, the connector board being located at the back side of the lower frame,
wherein video data is input from an external source to the connector board.
2. The liquid crystal display device according to claim 1 , wherein a width of the connector board is set smaller than a width of terminal of the connector.
3. The liquid crystal display device according to claim 1 , wherein the connector board comprises a bundle of cables, and the bundle of cables is fixed to the back side of the lower frame.
4. The liquid crystal display device according to claim 2 , wherein the connector board comprised bundle of cables, and the bundle of cables is fixed to the back side of the lower frame.
