[0002] At present, the conventional assembly of ordinary CRT TVs is that the high-voltage cap is assembled upwards, but because a safe distance is left between the high-voltage cap and the top of the casing when the upward assembly is made, certain constraints are imposed on the appearance design. In this structure, when the TV is assembled, various Components, especially the structure and arrangement of the circuit board, need to be designed for the high-voltage cap upward assembly, so the shape and internal structure of the TV are inflexible

Embodiment Construction
[0015] Such as Figure 1~3 As shown, in an embodiment of the novel TV set of the present invention, it includes a casing, a picture tube and a circuit board, and the picture tube is installed in the casing upside down, as figure 1 As shown, after the picture tube is inverted, its cone 21, deflection coil 22 and high-voltage cap 23 will be inverted as a whole. Through such an installation method, there is no need to reserve a safe space on the top of the casing, so that the TV The shape can be further reduced. At this time, in order to avoid the situation that the displayed image will be inverted up, down, left and right due to the inversion of the picture tube, the H+ output terminal and the H- input terminal of the row scanning circuit are respectively connected to the deflection coil. The H2 port is connected to the H1 port, and the V+ output terminal and the V- input terminal of the field scanning circuit are respectively connected to the V2 port and the V1 port of the defl...

The invention relates to a novel TV set which comprises a shell, a kinescope and a circuit main board, wherein the kinescope is inversely installed in the shell; the circuit main board comprises a line scanning circuit and a field scanning circuit; the kinescope comprises a deflecting coil; the H+ output end and the H-input end of the line scanning circuit are respectively connected with an H2 port and an H1 port of the deflecting coil; and the V+ output end and the V-input end of the field scanning circuit are respectively connected with a V2 port and a V1 port of the deflecting coil. By inversely mounting the kinescope, downwards assembling a high-voltage cap and fully utilizing a space between a core board and the high-voltage cap, the problem of restriction on the shell structure of the TV set caused by retaining a safe distance between the high-voltage cap and the top of the shell when the kinescope is upwards assembled is solved. Meanwhile, the invention also avoids the strikinghidden danger which probably existing in elements on the high-voltage cap and the core board, probable abnormal interference to the circuit main board by the high-voltage cap, and the like.
Description
technical field [0001] The present invention relates to a television set, and more particularly relates to a new type of television set. Background technique [0002] At present, the conventional assembly of ordinary CRT TVs is that the high-voltage cap is assembled upwards, but because a safe distance is left between the high-voltage cap and the top of the casing when the upward assembly is made, certain constraints are imposed on the appearance design. In this structure, when the TV is assembled, various Components, especially the structure and arrangement of the circuit board, all need to be designed for the assembly of the high-voltage cap upwards, so that the shape and internal structure of the TV set lack flexibility. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a new type of TV set in view of the lack of flexibility in design of the shape and internal structure of the TV set in the prior art.
